Single-neutron states in {sup 101}Sn.
A search for {gamma}-ray transitions in {sup 101}Sn, which contains only one neutron outside the {sup 100}Sn core, was carried out a tthe Argonne Tandem-Linac Accelerator System. {sup 101}Sn nuclei were produced using the {sup 46}Ti({sup 58}Ni, 3n){sup 101}Sn reaction. In-beam {gamma} rays were detected in the Gammasphere Ge-detector array and were correlated with {sup 101}Sn {beta}-delayed protons using the Recoil-Decay Tagging method. A {gamma}-ray line at 172 keV was assigned to {sup 101}Sn and was interpreted as the transition between the single-neutron g{sub 7/2} and d{sub 5/2} states. The measured {nu}g{sub 7/2{sup -}}{nu}{sup d{sub 5/2}} energy splitting is compared with predictions of various mean-field potentials. It is also used to calculate multi-neutron configurations in light Sn isotopes. Prospects of using {beta}-delayed protons for tagging other exotic nuclei in the {sup 100}Sn region are discussed.
