Abstract:
The region of the nuclear chart around A~100 is an area of structural changes where different shapes coexist and therefore, an interesting place to study structural evolution and test nuclear models. Within the clement that populate this region, zirconium is one which is expected to present well deformed states, but for which little experimental data has been measured so far. The structure of the 102-108Zr nuclei has been studied using the Interactiug Boson Model (IBM). Energy states and transition probabilities have been predicted and tested using the limited amount of existing experimental data. However, the results of these calculations produced several possibilities, so knowledge about non-yrast. states is needed in order to deepen the understanding of the structural changes in zirconium nuclei. Therefore a. series of experiments to measure non-yrast states of 102- 108Zr are required. A new technique, for separating different states of nuclei, has been developed and tested at the University of Jyvaskyla, using the IGISOL III facility for the known case of 100Nb β-decay into 100 Mo. This technique has been successfully extended to allow the separate study of the gamma.-ray decay of states populated by the different parent states. Lower spin states of 102- 108Zr are populated via beta-decay from 102- 108y' In order to measure the non-yrast states of 102- 108Zr post-trap online spectroscopy will be used at IGISOL IV. IGISOL IV is the improved version of IGISOL 111 and is currently under construction. Part of my Ph.D. consisted of helping with the development of IGISOL IV, the improvements of this facility are explained in this thesis alongside its operation and several tests performed during 2012.
