On the problems of creating a nuclear-optical frequency standard based on 229Th
F. F. Karpeshin, L. F. Vitushkin
The most probable candidate for the role of a nuclear optical standard is the 8.338-eV isomer of the 229mTh isotope of the thorium nucleus. Ways of using the resonance properties o…
Prospects for study of the effect of the electronic screening on the decay in the storage rings
F. F. Karpeshin, M. B. Trzhaskovskaya, L. F. Vitushkin
Study of the role of the electron screening in the decay is advanced, aimed at the experimental test in the storage rings. To this end, systematic calculation of the effect in…
Effect of electron screening on the decay
F. F. Karpeshin, M. B. Trzhaskovskaya, L. F. Vitushkin
The physical principles that determine the effect of the electron shell of an atom on the alpha decay rate of the nucleus are presented. The effect is shown to be negative. Numeric…
The non-resonance shake mechanism of the neutrinoless double electronic capture
F. F. Karpeshin, M. B. Trzhaskovskaya, L. F. Vitushkin
It is generally accepted that double neutrinoless electron capture is a resonance process. The calculations of the probability of shaking with the ionization of the electron shell…
On the E2 admixture in the deexcitation of the 229mTh isomer
F. F. Karpeshin, M. B. Trzhaskovskaya, L. F. Vitushkin
Latest experimental data on the properties of the 229Th nuclide isomer are analyzed. Deduced are the lifetime and the E2-fraction in its electromagnetic deexcitation, based on the…
