Überprüfung phänomenologischer und mikroskopischer Modelle zur Beschreibung nuklearer Leveldichten

Examination of phenomenological and microscopic models for the description of nuclear level densities

Master Thesis

Nuclear level densities are a central quantity in the description of statistical processes in atomic nuclei and have an important role in the modelling of nucleosynthesis.

Recently, a new experimental measurement method was developed and applied for the first time that allows to determine nuclear level densities in photonuclear reactions. For this, the method of nuclear self-absorption was employed. The experiment was conducted at the High Intensity Gamma-ray Source at Duke University, USA with the nuclide Sr-88.

This master thesis focuses on the analysis of the taken data with the objective to determine the nuclear level densities of Sr-88. Subsequently, existing phenomenological models and microscopic calculations shall be tested with the newly measured data. With this work, the student will contribute significantly to the research area for the investigation of statistical nuclear processes and provide potentially new results not existing before.
