Thermostatic properties of Seyler-Blanchard nuclei

Employing a recently developed semiclassical nuclear model, based on a modified Seyler-Blanchard interaction depending on both momentum and density, we consider the thermostatic properties of hot isosymmetric nuclei embedded in a nucleon vapor. The level-density parameter is calculated and discussed. Simple analytical expansions are obtained for the dependence of the level-density parameter and the free energy on nuclear mass number and the temperature of the surrounding vapor. The model is employed for an illustrative study of the symmetric breakup of 120Sn into a number of equal fragments
