Abstract
A theoretical study is made of the gross behavior of beta decays following nuclear fission in times from to 10 sec. First a simple model is formulated to describe the situation in terms of a few parameters. Then the most uncertain of these parameters are chosen to fit the observed rate of delayed gamma emission (assumed proportional to the beta-decay rate) for the process. The description is extended to other isotopes by assuming that they differ only by small shifts of their initial fragment distributions away from that appropriate to neutron-induced fission of . The result is a theoretical summary of the presently available data which can be used in predictive extrapolation of that data to situations not yet studied experimentally.
