Description
Laser spectroscopy performed at ISOLDE, CERN has been revolutionised by the installation of an ion beam cooler, ISCOOL. This device, a gas-filled linear RFQ, serves not only to improve the beam quality but also delivers a bunched ion beam. Recent measurements on isotopes of gallium (Z=31) are presented which illustrate the improvement. The phenomenon of monopole migration is the primary physics motivation in these studies - specifically the movement of proton states as the g9/2 neutron orbit is filled. The nuclear spin, magnetic moment, quadrupole moment and mean-square charge radius are complementary probes and all are obtainable from optical spectroscopy. Anomalous ground state spins have been measured for A=73 and A=81, and these, together with the moments, are compared with theoretical calculations.
