The main idea of the evaporation technique is that the differential cross section for the emission of a particle from a compound nucleus is proportional to the appropriate transmission coefficient and NLD. Therefore, the detailed shape of the particle spectrum is determined by the energy dependence of the level density. Further improvement of the experimental level density can be achieved by comparing the experimental spectra to those calculated with the Hauser-Feshbach theory and adjusting the theory parameters to reproduce the experimental spectra. In this talk, we present details on the experimental setup, analysis, and preliminary results for the measurement of 68Zn(n,a)65Ni and 68Zn(n,p)68Cu reaction cross section and the extraction of the nuclear level density of 68Cu and 65Ni.
