g Factors of High-Spin Yrast Traps in Gd 1 4 6 , 1 4 7

Pulsed beams of $^{28}\mathrm{Si}$ and $^{4}\mathrm{He}$ were used to determine $g$ factors of eight isomeric states in $^{144,146,147,148}\mathrm{Gd}$ by the time-differential spin-rotation method. The results show that proton and neutron configurations contribute about equally to the generation of angular momenta of two high-spin yrast isomers in $^{146,147}\mathrm{Gd}$ ($I\ensuremath{\sim}19 \mathrm{and} \frac{49}{2}$) whose detailed quasiparticle structure is suggested.
