We calculate the nuclear level density parameter a for a broad range of temperatures [Formula Presented] using a microscopic model which includes important ingredients like the thermal and quantal fluctuations of nuclear shapes, continuum corrections, and Coulomb interaction. Numerical calculations have been performed for [Formula Presented] and [Formula Presented] in a large model space. We find that at low temperatures, shell effects are larger for [Formula Presented] and effects of quantal fluctuations are larger for [Formula Presented] As temperature increases, these effects tend to disappear and continuum corrections become important for [Formula Presented]. © 1998 The American Physical Society.
