Nuclear moment measurements at NSCL

Building 6008 Conference Room

Electromagnetic moments can serve to stringently test nuclear structure models by providing important details on the composition of state wavefunctions and the charge distribution within the nucleus. In years past, we have used the method of beta-detected nuclear magnetic resonance on spin-polarized beams of rare isotopes to deduce ground-state magnetic dipole and electric quadrupole moments of neutron-deficient nuclei. More recently, we have installed and commissioned a beam line to perform collinear laser spectroscopy on rare isotopes initially produced by projectile fragmentation and converted to a low-energy (60 kV) beam following thermalization in a gas cell. I will discuss the past successes and future prospects in the study of nuclear moments of short-lived radioisotopes at NSCL.
