Catalysis of Fission Isomer Decay in the Coulomb Field of a Foil Nucleus for Ternary System of *2*5*2Cf / F.O.Otakhonov, Sh.A.Kalandarov, A.A.Shoymardonov // Физика элементарных частиц и атомного ядра. Письма. – 2026. – Т. 23, № 5. – P. 468. – URL: https://www1.jinr.ru/Pepan_letters/panl_2026_5/07_Otakhonov_ann.pdf.

We investigate the decay of fission isomers formed in spontaneous fission of &sup(252)Cf. Within the framework of trinuclear system (TNS) model, we describe the formation of the TNS and its decay, with subsequent formation of fission isomer as a dinuclear system (DNS). The modification of DNS half-lives is calculated using a quantum-mechanical tunneling approach. Our calculations reveal a dramatic catalytic effect of the external Coulomb field on the decay process of the DNS. The study bridges the gap between theoretical predictions and experimental observations, providing a comprehensive understanding of this fascinating nuclear decay phenomenon.
