YRAST STRUCTURE OF ~(97)Zr

摘要

The yrast structure of the neutron-rich nucleus ~(97)Zr has been studied using fission of target-like products in the reaction of a ~(48)Ca beam on a thick ~(238)U target. The level scheme known from the previous studies up to an energy and spin of approx. 4619 keV and 23/2~-, respectively, has been extended by about 3 MeV and a few units of angular momentum. The located structure can be discussed in terms of shell model configurations.
