Magnetic moments near A=100 and the tidal wave description of transitional nuclei near A=100

Andrew Stuchbery, Australian National University, Canberra, Australia
Building 6008 Conference Room

Frauendorf and collaborators have recently introduced a version of the cranking model applicable to transitional nuclei such as the isotopes of Ru, Pd and Cd with mass near 100. In this model the yrast states are treated as quadrupole waves running over the nuclear surface like a tidal wave over the ocean's surface. To test this model required much improved experimental g factors for nuclei in the A=100 region. I will describe our new transient-field g-factor measurements on several isotopes of Ru, Pd and Cd, and compare them with the 'tidal' model. An update will also be given on g factor measurements at the Australian National University, related to the radioactive beam g-factor programs at NSCL and HRIBF.
