Structure above the $t_{1/2}$ = 6.85-h, 21/2$^+$ isomer in $^{93}$Mo

ORAL

Abstract

Excited states in $^{93}$Mo were populated in the $^{90}$Zr($^{7}$Li,$p3n$) reaction at the Heavy-Ion Accelerator Facility of the Australian National University. The CAESAR array of nine coaxial HPGe detectors and two low-energy photon spectrometers (LEPSs) was used to detect the emitted gamma rays. Relative yields for population of the 21/2$^+$, $^{93m}$Mo state and neighboring reaction channels were determined from gamma-singles data for beam energies of 5 to 8 MeV/$A$. The level structure above the isomer has been expanded through gamma-gamma coincidence measurements. These results will be compared with high-spin structure of neighboring nuclei and with shell-model calculations.
