What can ($^{3}$He,d) tell us about the structure of $^{186,188}$Os
ORAL
Abstract
The structure of Os nuclei are of interest for a number of reasons including a debate over the vibrational nature of the K$^{\pi}$=4$^{+}$ bands, and a shape transition from well-deformed prolate to $\gamma$-soft oblate as the number of neutrons increases. In order to investigate the structure of $^{186,188}$Os, we have performed a ($^{3}$He,d) reaction on targets of $^{185,187}$Re. The 30 MeV $^{3}$He beams were obtained from the LMU/TUM Tandem Accelerator facility, and the Q3D spectrometer was used to analyze deuterons with 13 keV energy resolution. The absolute cross sections were measured at 9 angles from 5$^{\circ}$ to 50$^{\circ}$ up to $\sim$3 MeV in excitation energy. Fingerprint patterns are used to identify orbitals coupled to the 5/2$^{+}$[402]$_{\pi}$ target configuration.
