Description
The cross sections and analyzing powers of the 16O(p,p')16O(0-,T = 1) scattering were measured at a bombarding energy of 295 MeV and an angular range of 14 deg. ≤ θlab ≤ 30 deg. The isovector 0- state at Ex 12.80 MeV is clearly separated from the neighboring states with an energy resolution of ΔE ≅ 30 keV. The data have been compared with distorted wave impulse approximation (DWIA) calculations. The analyzing powers are sensitive to the effective nucleon-nucleon (NN) interaction used in DWIA calculations, and our data support the medium modification of the NN interaction in nuclei. The DWIA calculation employing a random phase approximation (RPA) response function predicts an enhancement of the cross sections around a momentum transfer of q ≅ 1.7 fm-1, and it gives a reasonable agreement with the data
