Title: Near spherical shell-model structure of the 2{sub 1}{sup +} state in {sup 40}Ar from g-factor measurements

Abstract

The g factor of the 2{sub 1}{sup +} state in {sup 40}Ar has been measured by use of Coulomb excitation in inverse kinematics and the transient magnetic-field technique. The resulting g factor, g(2{sub 1}{sup +})=-0.015(42), is in reasonable agreement with shell-model calculations within the (full sd){sub {pi}}(full fp){sub {nu}} space, without including core excitations. Although highly deformed admixtures in the wave function cannot be completely ruled out, they are small, in contrast to the case of {sup 42}Ca.
