PROBING SINGLE-NEUTRON LEVELS IN ~(127,129)Sn VIA TRANSFER REACTIONS

摘要

The (d,p) reaction was measured with radioactive ion beams of ~(126)Sn and ~(128)Sn (~5 MeV/u) in inverse kinematics at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory, utilizing the SuperORRUBA silicon detector array. Angular distributions of reaction protons were measured for several states in ~(127)Sn and ~(129)Sn in order to determine angular momentum transfers and deduce spectroscopic factors. Combined with previous experiments on ~(130)Sn and ~(132)Sn,these results provide a complete set of (d,p) reaction data on even tin isotopes between stable ~(124)Sn and doubly magic ~(132)Sn.
