We have measured 16O(p,d) reaction using 198-, 295- and 392-MeV proton beams to search for a direct evidence on the effect of tensor interactions in light nucleus. Differential cross sections one-neutron transfer reactions populating ground states several low-lying excited 15O were measured. Comparing ratios each state one over wide range momentum transfer, we found marked enhancement positive-parity state(s). The observation indicates large components high-momentum neutrons initial ground-state configurations, due possibly interactions.
