Quantum statistical calculation of cluster abundances in hot dense matter

Abstract

The cluster abundances are calculated from a quantum statistical approach taking into account in-medium corrections. For arbitrary cluster size the self-energy and Pauli blocking shifts are considered. Exploratory calculations are performed for symmetric matter at temperature $T=5$ MeV and baryon density $\varrho =0.0156$ fm${}^{-3}$ to be compared with the solar element distribution. It is shown that the abundances of weakly bound nuclei with mass number $4<A<12$ are strongly suppressed due to Pauli blocking effects.
