Abstract The odd- A platinum isotopes 78 191, 193, 195, 197pt have been populated by means of the (τ, α) reaction at E τ = 50 MeV. Spectra covering a range of 4 MeV of excitation energy were obtained. Angular distributions for levels in this excitation range have been deduced. Only a few 13 2 + states are strongly populated in each isotope, the actual number being 1, 2, 3, and 2 for A = 191, 193, 195 and 197 respectively. The spacing between these peaks exhibits an interesting variation with neutron number. The data are compared with predictions of current quasiparticle-core coupling models.
