Abstract

In a recent study, Perez Velasquez, Caballero, and Kelkar report a dramatically enhanced α decay rate of the nucleus 212Po at high temperatures which reaches almost five orders of magnitude at a temperature of 2 Giga-Kelvin. Contrary to that finding, only a moderate enhancement by a factor of three is found in the present comment which is based on a careful study of the properties of excited states in 212Po.

对“热激发核的α衰变”的评论

在最近的一项研究中，Perez Velasquez、Caballero和Kelkar报道了212Po核在高温下的α衰变率显著增强，在2吉开尔文的温度下达到了近5个数量级。与这一发现相反，在本评论中只发现了三倍的适度增强，该评论是基于对212Po激发态性质的仔细研究。
