Nucleon-nucleon correlations in dense nuclear matter; Nukleon-Nukleon-Korrelationen in dichter Kernmaterie

Abstract

In this thesis new results on the problematics of the formation of nucleon-nucleon correlations in nuclear matter could be presented. Starting from a general study of the two-particle problem in matter we studied the occurrence of a suprafluid phase (pair condensate of nucleons). The Gorkov decoupling by means of anomalous Green functions was generalized, so that also Cooper pairs with spin 1 (triplet pairing) can be described. A generalized gap equation resulted, which permits to determine the order parameters of the suprafluied phase in arbitrary channels of the nucleon-nucleon scattering states. This equation was solvd in the {sup 1}S{sub 0}-, in the {sup 3}P{sub 2}-{sup 3}F{sub 2}, and in the {sup 3}S{sub 1}-{sup 3}D{sub 1} channel under application of realistic nucleon-nucleon potentials. The behaviour of the resulting gap parameters in the single channels was studied as function of density and temperature. (orig.).

Das Verhalten der resultierenden Gap-Parameter in den einzelnen Kanaelen wurde als Funktion der Dichte und Temperatur untersucht. (orig.).}
