| مستخلص: |
The effect of temperature T and angular momentum J on the inverse level density parameter k has been studied by populating the compound nucleus 97Tc in the reaction 4He + 93Nb at four incident beam energies of 28, 35, 42, and 50 MeV. For all four energies, the value of k decreases with increasing J. The T dependence of k 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 J but deviate from all the calculations at lower J. [ABSTRACT FROM AUTHOR] |
