Internal conversion electrons and gamma-rays emitted in the decays of the neutron deficient gold isotopes with mass numbers 186--189 have been studied with a double focussing beta-ray spectrometer and a Ge(Li)detector. Multipolarities for the strongest transitions have been deduced. A revised level scheme for lS9pt is proposed. The haft-lives of 186Au, 188Au and 189Au are found to be (10.7__ 0.5), (9.0_+ 0.4) and (28.6_+ 1.0) minutes respectively.
