Final Report Abstract

In our initial proposal, we specified two major research interests. We were able to complete the first part of the project. The proposed 64 Zn(p,p’)64 Zn experiment was conducted and the data was analyzed. The results provided the basis for the PhD thesis of F. Diel and will be published as such. Theoretical predictions were performed and showed reasonable agreement with our results within some limitations. Our intended comparison of the results with the 64 Se beta decay was not possible because the data is still under evaluation. The investigation of the second part of our proposal is still incomplete. All data sets have been measured; however, we were not able to analyze them all. Some of the performed experiments are now being analyzed by our international partners.
