A Recoil-Beta Tagging (RBT) experiment was recently performed at the accelerator laboratory at the University of Jyvaeskylae in order to identify T = 1 excited states in the medium-heavy N = Z = 33 nucleus {sup 66}As. The fusion-evaporation reaction {sup 28}Si({sup 40}Ca,pn){sup 66}As was employed at a beam energy of 75 MeV. The experiment was carried out utilising the JUROGAM II {gamma}-ray spectrometer in conjunction with the gas-filled recoil separator RITU and the GREAT focal plane spectrometer system. The half-lives and ordering of the two known isomeric states in {sup 66}As have been determined. In addition, several new prompt {gamma}-ray transitions from excited states both bypassing and decaying to the isomeric states in {sup 66}As have been observed.
