g-factors of short-lived isomers in 147,148Gd and the role of the 3 − core excitation

The magnetic moments of short lived Gd isomers have been determined in a time differential measurement using the internal hyperfine field in ferromagnetic Gd host. The results g[ 147 Gd( 13 2 + )]=+ 0.075(3) and g[ 148 Gd(9 −)]=− 0.018(2) are discussed in terms of the contribution of the 3 − core ex...

Description
Summary:The magnetic moments of short lived Gd isomers have been determined in a time differential measurement using the internal hyperfine field in ferromagnetic Gd host. The results g[ 147 Gd( 13 2 + )]=+ 0.075(3) and g[ 148 Gd(9 −)]=− 0.018(2) are discussed in terms of the contribution of the 3 − core excitation. The 3 −⊗ vf7 2 n components in the respective wave functions are found to be dominant.
