Neutron capture ..gamma..-ray measurements have been performed upon enriched samples of /sup 118/Sn, /sup 116/Sn, and /sup 114/Sn following resonance capture. The ..gamma.. rays, measured with a Ge(Li) detector, have been incorporated in level schemes for /sup 119/Sn, /sup 117/Sn, and /sup 115/Sn. Spin and parity assignments have been made for many of the levels. Neutron separation energies for /sup 119/Sn, /sup 117/Sn, and /sup 115/Sn were determined to be 6484.6 +- 1.5, 6942.9 +- 2.0, and 7545.3 +- 2.0 keV, respectively. The level schemes have been compared with those of heavier Sn isotopes to investigate systematic behavior. Various spectroscopic properties (level energies, electromagnetic moments, and transition rates) of /sup 119/Sn, /sup 117/Sn, and /sup 115/Sn were calculated on the basis of a model which pictures these nuclei as being formed by coupling the motion of the odd neutron quasiparticle to the states of the neighboring even-mass core. The experimentally determined level properties of these Sn isotopes have been qualitatively reproduced by these calculations.
