Abstract
Excited states have been identified for the first time in very neutron defi cient Pt-171.172 nuclei using the recoil-or-decay tagging technique. The gr ound-state band in Pt-172 has been established up to I-pi = 8+. A similar l evel sequence, presumably built on the I-pi = 13/2(+) state, is observed fo r Pt-171. The data are compared with theoretical calculations based on the mean field approach and the random phase approximation and are put into the context of the systematics of platinum isotopes.
