Energy level density of nuclei Academic Article uri icon

abstract

  • We consider the calculation of the nuclear level density parameter a = 1 6π2gs(ε{lunate}F), where gs(ε{lunate}) is the smoothed single-particle level density and ε{lunate}F is the Fermi energy. We present an exact (quantum mechanical) calculation of gs(ε{lunate}) 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+h{stroke}2 correction and the local density approximation (LDA) are investigated using finite and infinite single-particle potential wells with sharp or smooth surfaces. © 1992.
