We report the first confirmation of the predicted inversion between the pi2p{sub 3/2} and pi1f{sub 5/2} nuclear states in the nug{sub 9/2} 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 {sup 71,73,75}Cu, which measured the nuclear spin and magnetic moments. The obtained values are mu({sup 71}Cu)=+2.2747(8)mu{sub N}, mu({sup 73}Cu)=+1.7426(8)mu{sub N}, and mu({sup 75}Cu)=+1.0062(13)mu{sub N} corresponding to spins I=3/2 for {sup 71,73}Cu and I=5/2 for {sup 75}Cu. The results are in fair agreement with large-scale shell-model calculations.
