【 摘 要 】

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 ρ = 0.0156 fm-3to be compared with the solar element distribution. It is shown that the abundances of weakly bound nuclei with mass number 4
