Level Densities of ^28Si, ^46Ti, ^52Cr and ^60Ni from Ericson Fluctuations
Abstract
Level densities in the continuum region are deduced in the compound nuclei of ^28Si, ^46Ti, ^52Cr and ^60Ni using thick target measurements and an Ericson fluctuation analysis of the reactions ^27Al(p,n), ^45Sc(p,n), ^51V(p,n) and ^59Co(p,n) respectively. A high resolution neutron spectra were measured in the range of neutron energies from 0.8 to 2.0 MeV with a bar of pastic scintillator viewed at both ends and the back by photomultipliers. Both NIM and CAMAC electronics were used in the electronic system. Time of flight techniques were used for the neutron identification with a flight path of 20 meters. Comparison of the deduced level densities with the most recent level density compilations will be also presented. This work was supported under U.S. D.O.E grant No. DE-FG02-88ER40387.
