Zusammenfassung / Abstract

The 'Lund-York-Cologne-Calorimeter' (LYCCA) is the first operational NUSTAR (Nuclear structure astrophysics and reactions) device for the HiSpec (High resolution in flight spectroscopy, starting in 2017) experiment at FAIR (Facility for anti proton and ion research). LYCCA is a high efficient detector array for identification and tracking of exotic nuclei and the design, testing and commissioning of LYCCA was the main part of this work.

A relativistic beam Coulomb excitation experiment using a radioactive beam was recently performed at GSI employing LYCCA, with the aim of measuring the reduced transition strengths (B(E2) values) of the first two excited states in Ar-33. The new experimental data is used to test effective interactions for shell model calculations.
