Gamma spectroscopy of low-energy isomeric states in neutron-rich nuclei: 75 Cu
Résumé
We present the results of an experiment in which the structure of neutron-rich nuclei located in the vicinity of N = 40 was studied. The importance of our results comes from the fact that knowing the behaviour of the neutron g9=2 orbital with increasing neutron number is one of the key points in defining the structure of these nuclei at low excitation energy. Preliminary results on the isomers of 75Cu will be presented together with tentative spin and parity assignments.
