Intuition
Near-neutrality changes the approach problem
A free electron or positron interacts strongly with surrounding electric fields. D is hypothesised to contain both charges in a configuration whose net external field is strongly suppressed at distances large compared with its internal separation.
If that suppression persists while D moves through matter, the pair might reach environments that a single charged particle would sample very differently. The new question is whether a sufficiently close D–nucleus encounter can alter the nuclear configuration.
The symbol on the right is deliberately not a known nuclear state. It marks the extra postulate: a D encounter has produced a configuration not present in the undisturbed sample.
The later beta event would not be truly spontaneous
If the disturbed nucleus later emits an electron or positron, the detector could register an apparently spontaneous increase in beta activity. In this hypothesis the event has a hidden history:
The first prediction is history dependence
For otherwise matched samples, the hypothesis expects the later anomalous component to depend on the previous population of electron–positron radiative events:
only in a regime where D production, transport and nuclear interaction are not saturated.
One signal is not enough
Ordinary radiation exposure can itself create nuclear backgrounds. A stronger D test therefore looks for two responses from the same hidden population: later probe-releasable electron–positron pairs and delayed beta-like activity. If one manipulation depletes or moves D, both effects should change coherently.
The Argument
The standard beta-decay benchmark
Standard nuclear data distinguish beta-minus, beta-plus and electron-capture channels by definite parent and daughter nuclides. Their measured masses determine Q-values, and the allowed decay pattern also depends on nuclear structure and transition rules.
A D hypothesis does not get to call any random electron or positron a beta decay. It must identify the daughter nuclide and reproduce the measured electron or positron spectrum, timing and accompanying radiation for the channel it claims to create.
The additional D–nucleus postulate
D existence alone does not imply nuclear instability. Add a separate interaction:
where \(N\) denotes a nucleus and \(\mathcal I_D\) is an unknown disturbance mechanism. Only if that interaction changes the nuclear state in a way that later permits charge-changing decay does the downstream prediction arise.
The ellipsis is not permission to ignore missing observables. A completed model must state the full measurable final state appropriate to the process.
The useful population model
If a fraction \(\eta_D\) of prior electron–positron radiative events produces D, write
using \(N_{\rm ann}\) only as the experimental event count normally labelled annihilations, without assuming the standard disappearance ontology.
If D survives with lifetime \(\tau_D\),
For a small interaction probability per D, an induced component could scale schematically as
where \(n_N\) is the density of candidate nuclei and \(\sigma_{DN}\) is an unknown effective D–nucleus interaction probability that the theory would have to derive.
Why annihilation-dose correlation is not enough
A sample exposed to more positrons or more high-frequency radiation can acquire ordinary activation or other radiation-induced changes. Therefore
is not by itself a D signature.
The stronger prediction is a shared hidden-state dependence:
and, conversely, a manipulation predicted to deplete D should reduce both while leaving ordinary activation backgrounds unchanged as far as the control design permits.
The experimental hierarchy
A useful programme therefore has three stages:
- establish a delayed, history-dependent probe-releasable electron–positron excess consistent with D;
- show that the same prepared samples develop an additional delayed beta-like component beyond standard activation predictions;
- identify specific daughter nuclides and demonstrate that both signals track a common D-population model under delay, material and depletion tests.
Deep Notes
This is a hypothesis downstream of a hypothesis. Titraj motivates D by treating the measured radiation of an electron–positron system as an output of charge motion rather than direct observation of constituent disappearance. D then proposes that the pair survives in a nearly neutral configuration. Nuclear instability requires one more statement: that this configuration can interact with a nucleus strongly enough to alter what happens later.
Keeping those steps separate is essential. A beta anomaly cannot retroactively prove Titraj, and it cannot even establish D unless an independent D-sensitive observable is present.
What standard nuclear data already constrain
Evaluated nuclear databases tabulate stable and unstable nuclides, daughter channels, half-lives, level schemes and beta Q-values. Ground-state beta Q-values are obtained from measured atomic masses, while transition probabilities depend additionally on the available nuclear states and weak-transition structure.
A D-induced event must therefore produce something identifiable at the nuclide level. It is not enough to detect an electron. For a proposed candidate isotope the experiment should determine:
- which daughter nuclide appears;
- whether the electron or positron spectrum matches that daughter channel;
- whether associated gamma lines or other de-excitation signatures appear;
- how the rate evolves after the D-producing exposure;
- and whether ordinary activation mechanisms can account for the same products.
Stable does not mean immune to external reactions
A nucleus called stable is stable against the spontaneous decay channels accessible under ordinary conditions. Stable material can still undergo nuclear reactions when struck by suitable particles or radiation. Therefore the D proposal is not logically “a stable nucleus suddenly violates stability.” It is an unestablished external nuclear interaction with a hidden projectile or bound configuration.
This distinction also makes the experimental burden clearer: standard photonuclear, positron-induced, neutron-induced, impurity and cosmic backgrounds must be measured or modelled rather than subtracted by assumption.
The correlation with previous electron–positron events
Let the experimentally counted prior radiative events be \(N_{ann}\). The D hypothesis predicts a stored population
If D is stable over the experiment, \(N_D\) may persist; if metastable, its delay dependence supplies a direct test. Nuclear interactions then remove or transform some fraction of that population:
This schematic equation is not a derived D dynamics. It simply exposes experimentally different loss channels: spontaneous D loss, nuclear interaction and deliberate breakup.
A depletion experiment is stronger than a dose experiment
Prepare two matched samples with the same prior positron and annihilation history. After the prompt radiative window, apply to one sample a treatment that a future D model predicts will break up, extract or otherwise deplete D while minimising nuclear activation. Leave the other sample untreated or apply a sham treatment with matched ordinary dose.
The D hypothesis then predicts
followed by
If the same depletion treatment also produces a measurable release of electron–positron pairs, the two observables become linked:
This anti-correlation would be more distinctive than a simple increase with irradiation dose.
Candidate nuclei must be selected before the measurement
A serious test cannot survey many elements and then identify whichever isotope happened to change. The model should choose candidate nuclei from a proposed D–nucleus interaction, predict the daughter channel and approximate scaling, and then test those targets prospectively.
The key observable bundle is
One D-population model should account for the whole bundle.
The clean falsifiable statement
If delayed beta activity is fully explained by known activation channels, does not correlate with an independently measured D-sensitive population, or fails to respond to a pre-specified D-depletion manipulation, this downstream hypothesis loses its intended support.
The boundary
There is currently no established evidence on this page that D exists or that it perturbs nuclei. The proposal is useful only because it turns the idea into a sequence of separable tests: first the hidden electron–positron configuration, then its nuclear interaction, then isotope-specific delayed decay signatures.
