How understanding nature made the atomic bomb inevitable
WebBohr-Wheeler's transition-state method and Kramers' dynamical model of nuclear fission, first pointed out by Strutinsky in 1973, is revisited. The study is based on studying the features of individual trajectories on the fission path. Introduction Fission is one of the most important decay channels of heavy nuclei, both cold and excited. It finally WebFeb 13, 2003 · A simple model for establishing the Bohr and Wheeler limit for Z2/A against spontaneous fission is developed.

We show that it is also possible to formulate the theory without the help of collective coordinates. In the new … WebNuclear fission is a complex process that involves the rearrangement of hundreds of nucleons in a single nucleus to produce two separate nuclei.
