Parity Measurements in $^{70}$Ge

Previous studies of the $^{70}$Ge nucleus have left open questions about its decay spectrum, in particular the spins and parities of the high-spin states. The goal of this work was thus to measure the parity of as many states in $^{70}$Ge as possible. High-spin states in $^{70}$Ge were produced from the $^{62}$Ni($^{14}$C,$\alpha 2n$) reaction at 50 MeV performed at Florida State University. The resulting $\gamma$ decays were measured in coincidence using a Compton-suppressed Ge array consisting of three Clover detectors and seven single-crystal detectors. The parallel and perpendicular Compton-scattering yields in a Clover detector (relative to the beam direction) were measured under the condition that another $\gamma$ decay in $^{70}$Ge was also detected in coincidence. Ultimately, the linear polarizations of eight transitions in $^{70}$Ge were measured, leading to the confirmation of eight parity assignments. In general, the linear polarization measurements for the low-spin transitions show good agreement with those measured previously as well as with theoretical predictions based on previous angular distribution measurements.
