Abstract

The neutron-deficient nucleus Sn-107 has been studied by using the one-neutron knockout reaction. By measuring the decay gamma rays and momentum distributions of reaction residues, the spins of the ground, 5/2(+), and first-excited, 7/2(+), states of Sn-107 have been assigned by comparisons to eikonal-model reaction calculations. Limits on the inclusive and exclusive cross sections have been measured and transitions due to neutron removals from below the N = 50 closed shell have been observed. New excited states up to 5.5 MeV in Sn-107 have been identified.
