Competing core and single particle excitations in the 2+1 state in 44Ca

Abstract The g factor of the 2 1 + state in 44 Ca has been measured using the transient field technique and Coulomb excitation in inverse kinematics. A positive value of g(2 1 + , 44 Ca )=+0.12±0.05 was deduced. The result suggests the ( fp ) 4 ν configuration competes with excitations of the 40 Ca core. A simple model which considers that the wave function for the 2 1 + state consists of approximately equal admixtures of spherical four valence neutron configurations and a deformed core configuration accounts for the experimentally observed g factor as well as the previously measured quadrupole moment.
