Transition Strengths in $^{67}$Ga
POSTER
Abstract
High-spin states in $^{67}$Ga were studied using the $^{55}$Mn($^{18}$O,$\alpha$2$n$) reaction at 50 MeV performed at Florida State University. Prompt $\gamma$-$\gamma$ coincidences were measured with a Compton-suppressed Ge array consisting of three Clover detectors and seven single-crystal detectors. The existing level scheme was verified based on the measured $\gamma$-$\gamma$ coincidences. Lifetimes of 13 excited states were measured using the Doppler-shift attenuation method. Reduced electric quadrupole transition rates $B$($E2$) were calculated from the lifetimes and compared with the predictions of the Interacting Boson-Fermion Plus Broken Pair Model (IBFBPM) from previous work. The evolution of shape with spin was inferred from cranked Woods-Saxon calculations.
