COMPLEX FRAGMENT EMISSION FROM LOW-ENERGY COMPOUND NUCLEUS DECAY TO MULTIFRAGMENTATION

In the first of these lectures, the experimental emission probabilitie s of complex fragments by low energy compound nuclei and their depende nce upon energy and Z value are compared to the transtion state rates. In the second part, the high energy multi-fragment emission probabili ties are shown to be reducible to the single fragment emission probabi lity through the binomial distribution. The extracted one-fragment emi ssion probabilities have a thermal dependence of the form p = e(-B/T). This suggests that multifragmentation is a sequence of thermal binary decays.
