The tensor open-shell random phase approximation with application to the even nickel isotopes

Abstract

The general tensor equations of motion are applied to the particle-hole excitation of a J ≠ 0 and/or T ≠ 0 system in the open-shell random phase approximation. Calculations are made for the negative-parity states of the J = 0, T ≠ 0 isotopes of nickel. Magnetic excitations, in particular, are investigated in terms of inelastic electron scattering and the possibility of observing M2 and M8 excitations is discussed.
