Description
Experiments to study nuclear moments in single and multi-nucleon transfer reactions have been carried out at the Tandem-ALTO facility of Orsay using the ORGAM spectrometer. Quadrupole moment measurement of the 6- isomeric state in 66Cu has been measured in a single nucleon transfer on a Cu2O host. As this state results from a week coupling between the πp3/2 and the ν g9/2 orbitals, leading to sizable deformation at oblate and prolate shapes in the 68Ni region, we have observed the interplay between these two different deformation-driving orbitals [1].
Furthermore, we have investigated the possibility of using multi-nucleon transfer reactions for the population and nuclear moment studies of isomeric states in 66Cu and 63Ni [2].
These studies could not only serve as a base for the determination of the unknown electric-field gradient of Cu in Zn e.g. via a quadrupole moment measurement, but would also allow the determination of the nuclear-spin orientation in these reactions. Therefore, investigations of this type open possibilities to employ nuclear moment measurements and transfer reactions to both on the neutron-deficient and neutron-rich side of the nuclear chart.
