摘要: In addition to the well-established quadrupole mixed-symmetry states, octupole and hexadecapole excitations with character have been recently proposed for N = 52 isotones 92Zr 94Mo. We performed two inelastic proton-scattering experiments study this kind of in heaviest stable isotone 96Ru. From combined experimental data both absolute transition strengths were extracted.
