Abstract

From the Fermi theory of $\ensuremath{\beta}$-disintegration the probability of simultaneous emission of two electrons (and two neutrinos) has been calculated. The result is that this process occurs sufficiently rarely to allow a half-life of over ${10}^{17}$ years for a nucleus, even if its isobar of atomic number different by 2 were more stable by 20 times the electron mass.

双衰变

从费米衰变理论出发，计算了同时发射两个电子(和两个中微子)的概率。结果是这个过程很少发生，使得原子核的半衰期超过${10}^{17}$年，即使它的原子序数相差2的等压线比电子质量的20倍更稳定。

期刊介绍： Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
