摘要: THROUGH the kindness of authors I have been informed content letters1 recently sent to Editor NATURE by Prof. Meitner and Dr. Frisch. In first letter, these propose an interpretation remarkable findings Hahn Strassmann as indication for a new type disintegration heavy nuclei, consisting in fission nucleus into two parts approximately equal masses charges with release enormous energy. second Frisch describes experiments which are directly detected very large ionization they produce. Due extreme importance this discovery, should be glad add few comments on mechanism process from point view general ideas, developed recent years, account main features nuclear reactions hitherto observed.
