Description
The neutron-rich A~100 region is known for a sudden change in nuclear shape deformation from nearly spherical to highly-deformed as A goes from 97 to 99. The most severe change (as measured by the electric quadrupole deformation parameter) seems to occur in the region centered on 98Y. To better understand this phenomenon, the magnetic moments (another probe of nuclear deformation) of the 2−1 and 4−1 isomeric states of 98Y have been measured using the Time-Differential Perturbed Angular Correlation (TDPAC) method on data collected from the Lohengrin fission fragment spectrometer at Institut Laue-Langevin. The results of the measurements have been compared to two theoretical calculations, the Interacting Boson Fermion Fermion Model (IBFFM) and the Complex Excited Vampir Model (EXVAM), which both compare somewhat favorably.
