摘要:

本文研究了152 Gd、164 Er和180 W原子的共振无中微子双电子俘获(0 nECEC)过程,以及基态到基态的核跃迁。相应的矩阵元计算内变形QRPA使用现实的Bonn-CD核子核子相互作用。使用这些过程的Q值的最新精密度数据估计半衰期。最后讨论了152 Gd、164 Er和180 W等同位素nECEC的实验研究前景。

英文摘要:

We study the resonant neutrinoless double-electron capture (0nECEC) in 152Gd, 164Er and 180W atoms, associated with the ground-state to ground-state nuclear transitions. The corresponding matrix elements are calculated within the deformed QRPA using the realistic Bonn-CD nucleon-nucleon interaction. The half-lives are estimated with the use of the most recent precision data on the Q-values of these processes. Perspectives of experimental search for the 0nECEC with the isotopes 152Gd, 164Er and 180W are discussed.
