Microscopic description of a low-lying Kπ = 1+ mode in 156Gd

Abstract

A recently observed Kπ = 1+ mode in deformed nuclei is studied microscopically. By calculating the energies, the B(M1)-values and the form-factors of inelastic electron scattering for 156Gd, we conclude that the relatively strong M1-strength observed at 3.075 MeV comes predominantly from the convection current of proton excitations in the Oh 1 2-orbit. We suggest a search for the M1-strength around 4 MeV, which arises from proton excitations in deformation-aligned orbits.
