Micropolyelectrons as possible sources of the anomalous positron peaks in heavy-ion reactions
We propose that aggregates of electrons and positrons in a small assembly (micropolyelectrons (e{sup +}e{sup {minus}}){sup n}), held together by their own electromagnetic interactions, are probably the sources of the anomalous positron peaks observed in heavy-ion reactions. The quasistability of the micropolyelectrons arises from a strong noncentral, short-range, attractive interaction between an electron and a positron in their 0{sup ++} state, which may be supercritical and may lead to a condensation of such pairs. These entities are strongly attracted to a nucleus with a large charge, due to the quadratic Coulomb interaction between the nucleus and the constituents, and may therefore have binding energies greater than their rest masses to render them spontaneously produced in a strong Coulomb field. Final-state interactions between the produced micropolyelectrons and the receding nuclei may lead to their being nearly at rest and back-to-back decay into e{sup +} and e{sup {minus}} in some cases, and their being captured into stationary orbits and asymmetrical decay in some other cases.
