Description
The series of copper isotopes (Z=29) is of prime interest for nuclear structure. The first 5/2 level in the odd isotopes, carrying most of the f5/2 proton strength, sharply drops in energy beyond N=40 and becomes the ground state in 75Cu. The position and the strength distribution of the f7/2 spin-orbit partner is essential to understand the underlying mechanism of this effect, bent to have major implications for structure variations towards 78Ni. With this purpose in mind the 72Zn(d,3He)71Cu transfer reaction was performed at Ganil with the Must-2 particle array, giving precisely access to proton-hole states in copper. The data are currently under analysis.
