Abstract

In a fusion-evaporation reaction the total gamma-energy and multiplicity after particle evaporation - the so-called entry distribution - can be used to estimate the height of the fission barrier as function of angular momentum. This method is especially favorable for unstable nuclei, for which the fission barrier is otherwise very difficult to measure. Here, we have measured the entry distributions of ²²⁰Th at beam energies of 206 MeV and 219.5 MeV in the ¹⁷⁶Yb(⁴⁸Ca,4n) reaction. The results are compared to a previous measurement using photofission.
