Inelastic proton scattering from Pt isotopes and the interacting boson model.

Inelastic proton scattering has been used to measure the {ital d}{sigma}/{ital d}{Omega} and {ital A}{sub {ital y}} angular distributions for several low-lying collective states in {sup 194,196}Pt using 647 MeV polarized protons with special emphasis on the excitation of the 4{sup +} states below 2 MeV. The data have been analyzed in the framework of the coupled-channels scheme using the program ECIS. Large {ital E}4 transition strengths to the 4{sup +} states in both nuclei are found in sharp contrast with the predictions of the interacting boson model with only {ital s} ({ital L}=0) and {ital d} ({ital L}=2) bosons. It is found that although the {ital E}2 properties of these nuclei are consistent with the interacting boson model ({ital sd}) predictions, higher degrees of freedom, e.g., {ital g} ({ital L}=4) bosons, need to be invoked in order to get a reasonable agreement with the measured {ital E}4 properties.
