Abstract

Nuclear reactions and decays belonging to a new class referred to as a virtual class since virtual intermediate states of \(A\geqslant 2\) atomic nuclei at off-shell energies are involved in the amplitude of the widths with respect to such processes are studied by considering examples of two-proton and double-beta decays of nuclei, as well as spontaneous ternary fission of even–even actinide nuclei. The widths and angular distributions are calculated for two-protom decays of nuclei, and the half-lives of nuclei with respect to double-beta decay are also determined. The radii of the neck in fissioning nuclei and the heat of the binary fission of the intermediate nucleus in the ground state for spontaneous ternary fission of \({}^{248}\)Cm, \({}^{250}\)Cf, and \({}^{252}\)Cf nuclei are estimated.

涉及中间核虚拟状态的新型核衰变

摘要

由于研究了壳外能的\（A \ geqslant 2 \）原子核的虚拟中间态涉及这种过程的宽度幅度，因此属于一个称为虚拟类的新类别的核反应和衰变通过考虑原子核的两个质子和双β衰变以及偶数-甚至act系原子核的自发三元裂变的例子。计算原子核的两个原子衰变的宽度和角度分布，并确定原子核相对于双β衰变的半衰期。自发三元裂变\（{} ^ {248} \） Cm，\（{} ^ {250} \）的裂变核的颈半径和基态中间核的二元裂变热Cf和\（{} ^ {252} \）估计Cf核。
