SPIN-FLIP ASYMMETRY IN THE PROTON INELASTIC SCATTERING TO THE FIRST 2+STATES OF48,50Ti

Angular distributions of the differential cross section σ (θ), analyzing power Ay (θ), spin-flip probability S(θ) and spin-flip asymmetry e (θ) in the excitation of the first 2+ states in 48Ti and 50Ti were measured at incident energies of 11 and 18 MeV using (p, p' γ) coincidence technique with polarized proton beam. The results were analyzed in terms of a macroscopic coupled channels method based on the vibrational model and of the microscopic distorted wave Born approximation (DWBA) based on shell-model wave functions and effective nucleon-nucleon interactions.
