I found and fixed some errors in the Mathematica document and also made some changes in the text. In its basic form, Peierls formulae are not useful for numerical calculations for the high-multiplication number regime (see URL ablove). In the derivation a substitution is made in order to be...
I am sure the detailed physics requires much better models than the first estimates that was published 1939 and in 1965, when the Los Alamos Primer was declassified. And I certainly hope that all the important aspects of building a nuclear device will continue to be classified. The reason for my...
Dear Forum,
this is my forst time here, so forgive me if I don't conform to any etiquette or rules.
When I did nuclear physics in undergraduate school many years ago, I couldn't help noticing that little or no information was ever given on he issue of neutron multiplication and...
