A Recoil‐Beta Tagging (RBT) experiment was recently performed at the accelerator laboratory at the University of Jyväskylä in order to identify T  =  1 excited states in the medium‐heavy N  =  Z  =  33 nucleus 66As. The fusion‐evaporation reaction 28Si(40Ca,pn)66As was employed at a beam energy of 75 MeV. The experiment was carried out utilising the JUROGAM II γ‐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 66As have been determined. In addition, several new prompt γ‐ray transitions from excited states both bypassing and decaying to the isomeric states in 66As have been observed.
