    A medium-spin isomer in Au197 is identified with t1/2=150(5) ns following a multinucleon transfer reaction between an 850-MeV Xe136 beam and a Pt198 target. The transitions identified here are considered and possible configurations for the associated levels discussed. In addition, a newly observed out-of-beam transition in Au195 is briefly reported. © 2006 The American Physical Society.
