Excited states of the stable nucleus Pt-195 have been studied using an in-beam gamma-ray spectroscopic technique following the incomplete fusion of Li-7 on an Os-192 target at 44 MeV. A level scheme built on the I-pi = 13/2(+) isomer has been established up to I-pi = 33/2(-) at an excitation energy of about 2.6 MeV. Spin and parity values of these states have been assigned from an analysis of anisotropy ratios of gamma rays and by analogy with the neighboring nuclei. A comparison of the observed structures with the yrast states in the neighboring even-even Pt-196 core indicates that the identified levels may be regarded as arising from the weak coupling of a nu i(13/2) neutron hole to the core states.Physics, NuclearSCI(E)0ARTICLE1null8
