    Abstract

    We report the first confirmation of the predicted inversion between the π2p3/2 and π1f5/2 nuclear states in the νg9/2 midshell. This was achieved at the ISOLDE facility, by using a combination of in-source laser spectroscopy and collinear laser spectroscopy on the ground states of Cu71,73,75, which measured the nuclear spin and magnetic moments. The obtained values are μ(Cu71)=+2.2747(8)μN, μ(Cu73)=+1.7426(8)μN, and μ(Cu75)=+1.0062(13)μN corresponding to spins I=3/2 for Cu71,73 and I=5/2 for Cu75. The results are in fair agreement with large-scale shell-model calculations.
