Level studies of 73As via 73Ge(p, nγ)73As reaction and density of discrete levels in 73As

Abstract

The excited states of 73As have been investigated via the 73Ge(p, nγ)73As reaction with the proton beam energies from 2.5-4.3 MeV. The parameters of the nuclear level density formula have been determined from the extensive and complete level scheme for 73As. The Bethe formula for the back-shifted Fermi gas model and the constant temperature model are compared with the experimental level densities.
