【正】 Angular distributions have been measured for the elastic and inelastic scattering and one-nucle-on transfer of 88.0 MeV <sup>16</sup>O on <sup>116</sup>Sn.Coupled-channels calculations have been performed for the elasticand inelastic scattering,and DWBA treatment for one-proton stripping(<sup>16</sup>O,<sup>15</sup>N),and one-neutron pick-up(<sup>16</sup>O,<sup>17</sup>O)reactions.Tne results compared with the previous 64 MeV ones show energy dependence inthe optical potentials and also in the normalization factors with the spectroscopic factors preserving consis-tent in DWBA analysis,which might relate to the threshold anomaly phenomena.
