Test of octupole coupled 5- state in 146Nd using proton inelastic scattering

Abstract

The inelastic scattering of 35 MeV protons has been used to excite seven states below 2.1 MeV in 146Nd. A comparison between a coupled-channels calculation that assumes an octupole coupled structure for the 5- state at 1.517 MeV and the observed cross section suggests that the wave function of this state includes only a small two-quasiparticle component. In addition, the present results indicate that the level at 2.073 MeV, previously assigned Jπ=4-, actually has Jπ=3-
