The purpose of this project was to analyze data from an experiment carried out at LNL (Legnaro National Laboratories) in order to test the collective nuclear model. In the experiment 170Dy was created by multi-nucleon transfer reactions. This isotope is predicted to be the most collective of all nuclei with A < 190. γ-ray energies originating from its deexcitation allow to measure its collectivity. The PRISMA spectrometer was used to determine which ions were produced in the reactions and AGATA measured the γ-radiation from these products. The analysis consists of a calibration process of all detectors and eventually leads to the identication of 170Dy and of its deexcitation energies. This report explains the analysis procedure and some of the steps to identify the reaction prodcuts and corresponding γ-ray energies were performed. Xe-isotopes and corresponding γ-spectra have been identied.
