Mixed-symmetry octupole and hexadecapole excitations in N=52 isotones

Abstract

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