Enhancement Mechanisms of Low-Energy Nuclear Reactions

“…For neutral 187 Re 0+ only a unique, first forbidden transition to the 187 Os ground state is energetically possible. The small matrix element and the small Q β value of Q β =2.663 (19) keV lead to the long half-life of 42 Gyr. The measured half-life [45] for bare 187 Re 75+ (Q K βb =+72.97 keV) of T 1/2 = (32.9 ± 2.0) yr is billion times shorter than that for neutral 187 Re.…”

“…It can be carried out in different macroscopic ways by using available environmental effects. These questions were highlighted in different reviews and books [2,13,14,15,16,17,18,19] at the end of the seventies of the 20th century. The reader should compare the common by accepted conclusions about the decay rates in the thirties and seventies of the 20th century.…”
