GYROMAGNETIC RATIOS IN NEUTRON-RICH NUCLEI BY THE RECOIL IN VACUUM TECHNIQUE

摘要

New g-factor measurements by the recoil in vacuum method are discussed. The stable even tin isotopes, neutron-rich ~(126,128)Sn,and tellurium isotopes including neutron-rich semi magic ~(134)Te, have been studied. The experiments were performed at the Holifield Radioactive Ion Beam Facility (HRIBF) by Coulomb exciting ~3 MeV/u beams in inverse kinematics on C and Ti targets, and using the CLARION+HyBall arrays to observe the perturbed particle-angular correlations. The measurements, including those on the neutron-rich radioactive beams, have sufficient precision to distinguish between alternative models.
