Moment measurements of exotic nuclei

A program directed towards the measurement of ground state moments in nuclei far from stability has been initiated at the National Superconducting Cyclotron Laboratory at Michigan State University. Spin-polarized fragments are produced at small angles relative to the primary beam axis by intermediate-energy heavy-ion reactions. The fragments are collected and analyzed using the A1200 fragment separator. The β-NMR technique is then used to detect the resonance frequency of the spin-polarized exotic fragments. The results of the first experiments using the β-NMR system recently installed at the NSCL will be reported, including measurements of the polarization of 12B fragments following the reaction of 18O at 80 MeV/A on a Nb target.
