Abstract
The effect of temperature and angular momentum on the inverse level density parameter has been studied by populating the compound nucleus in the reaction at four incident beam energies of 28, 35, 42, and 50 MeV. For all four energies, the value of decreases with increasing . The dependence of has been compared for two angular momentum windows with different theoretical predictions as well as with the finite-temperature BCS calculation which takes into account the quasiparticle-number fluctuations in the pairing field (FTBCS1). Interestingly, the experimental data are in good agreement with the theoretical calculations at higher but deviate from all the calculations at lower .
