Abstract
Correlation effects in nuclear matter at finite temperatures are studied for subnuclear densities ($\rho<\rho_0$) and medium excitation energy, where a nonrelativistic potential approach is possible. A quantum statistical approach is given, where clusters are treated under the influence of a clustered medium treated within a mean field approximation. Spectral functions, in-medium cross sections, and reaction rates are considered as well as the formation of a quantum condensate. In particluar, exploratory calculations are shown with respect to the pseudo gap in the nucleon level density close to the superfluid phase transition. Estimates of isospin singlet pairing and quartetting in nuclear binding energies are given.
