Role of antisymmetrization in describing the excitation of the 1(+), T=1 level in the C-12 nucleus by polarized protons

摘要

Inelastic polarized-proton scattering involving the excitation of the 1(+), T = 1 level at 15.11 MeV in the C-12 nucleus is described within the distorted-wave method. The effect of completely or approximately taking into account the antisymmetrization of the wave function for the projectile proton-intranuclear nucleons system on various observables, including the differential reaction cross section, the analyzing power, the difference of the polarization and analyzing power, and the depolarization parameter, is analyzed. The difference of the polarization and the analyzing power in the case of the excitation of anomalous-parity levels is shown to be especially sensitive to taking into account the above antisymmetrization. The reason for a large value of this difference for the level being studied and the sensitivity of this value to the parameters of the effective nucleon-nucleon interaction used are analyzed.
