Collective model for the description of low-energetic heavy-ion collisions; Kollektives Modell zur Beschreibung niederenergetischer Schwerionenstoesse

Abstract

The aim of the thesis consisted in a collective description of heavy-ion collisions near the Coulomb barrier. Thereby first under use of present nuclear-physical knowledge it should be decided wether the application of a collective model seems generally to be senseful and which degrees of freedom should be regarded. With regards to the spontaneous vacuum decay our special point of view was dedicated to the possible existence of very large nuclear contraction times as well as to the question wether their are measurement quantities, which can be applied as trigger for extremely time-delayed heavy-ion collisions. In this connection we have especially studied the mass transfer between the colliding ions. First we have applied the asymmetric two-center shell model. The first approximation by means of the asymmetric two-center shell model can be absolutely designated as successful. The Wilczynski diagrams for {sup 86}Kr+{sup 166}Er and {sup 208}Pb+{sup 208}Pb collisions can be sufficiently described and have been used to the fitting of the classical friction parameters.
