Excited states of the stable nucleus {sup 195}Pt have been studied using an in-beam {gamma}-ray spectroscopic technique following the incomplete fusion of {sup 7}Li on an {sup 192}Os target at 44 MeV. A level scheme built on the I{sup {pi}=}13/2{sup +} isomer has been established up to I{sup {pi}=}33/2{sup -} 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 {sup 196}Pt core indicates that the identified levels may be regarded as arising from the weak coupling of a {nu}i{sub 13/2} neutron hole to the core states.
