gbosons and the third4+state inOs192

Reduced matrix elements for excitation of the first three $4^{+}$ states in ${}_{}{}^{192}{}_{}{}^{}\mathrm{Os}$ have been measured using inelastic scattering of 135 MeV polarized protons. These data, as well as the known quadrupole properties of ${}_{}{}^{192}{}_{}{}^{}\mathrm{Os}$, are best described if the third $4^{+}$ state is interpreted as a g-boson intruder state.
