Gamow-teller strength and particle-phonon states in149Dy from decay of its 11/2- and l/2+ 149Ho parents
Abstract
Studies of the149Ho 11/2- and 1/2+ GT-decays using on-line mass separation have established in the N=83149Dy nucleus the single neutron excitations below 1.8 MeV and members of the νf7/2×3- and νf7/2×2+ particle-phonon multiplets. Quantitative analysis of the GT-decay strength to149Dy 1qp- and 3qp-states is made in terms of the strength values measured in149Dy0 and147Tb11/2- decay.
