Abstract

Excited states of the stable nucleus 195Pt have been studied using an in-beam γ-ray spectroscopic technique following the incomplete fusion of 7Li on an 192Os target at 44 MeV. A level scheme built on the Iπ=13/2 ⁺ isomer has been established up to Iπ=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 γ rays and by analogy with the neighboring nuclei. A comparison of the observed structures with the yrast states in the neighboring even-even 196Pt core indicates that the identified levels may be regarded as arising from the weak coupling of a νi_13/2 neutron hole to the core states.
