Laser-spectroscopy studies of the nuclear structure of neutron-rich radium

K.M. Lynch et al.

The neutron-rich radium isotopes, Ra222233, were measured with Collinear Resonance Ionization Spectroscopy (CRIS) at the ISOLDE facility, CERN. The hyperfine structure of the 7s2S017s7pP13 transition was probed, allowing measurement of the magnetic moments, quadrupole moments, and changes in mean-square charge radii. These results are compared to existing literature values, and the new moments and change in mean-square charge radii of Ra231 are presented. Low-resolution laser spectroscopy of the very neutron-rich Ra233 has allowed the isotope shift and relative charge radius to be determined for the first time.
