Statistical Multifragmentation Model within the Extended Morphological Thermodynamics Approach

Abstract

On the basis of morphological thermodynamics we develop an exactly solvable version of statistical mutifragmentation model for the nuclear liquid-gas phase transition. It is shown that the hard-core repulsion between spherical nuclei generates only the bulk (volume), surface and curvature parts of the free energy of the nucleus, while the Gaussian curvature one does not appear in the derivation. The phase diagram of nuclear liquid-gas phase transition is studied for a truncated version of the developed model.Comment: Talk given at XIX Igor Sikorsky Kyiv Polytechnic Institute Conference "Theoretical and Practical Problems of Physics, Mathematics and Informatics" , May 13-14, 2021, Kyiv, Ukraine (4 pages, 2 figures
