Abstract: (Elsevier)
We consider the calculation of the nuclear level density parameter a = 1 6 π 2 g s (ϵ F ) , where g s ( ϵ ) is the smoothed single-particle level density and ϵ F is the Fermi energy. We present an exact (quantum mechanical) calculation of g s ( ϵ ) for bound and continuum states using a Green function approach with Strutinski smoothing. The accuracy and applicability of semiclassical approximations, such as the Thomas-Fermi (TF), TF+ħ 2 correction and the local density approximation (LDA) are investigated using finite and infinite single-particle potential wells with sharp or smooth surfaces.
