Abstract:

The polarizations and triple scattering parameters of the nucleons elastically scattered from light nuclei are explained with the optical model potential by the use of the nucleon-nucleon scattering phase shifts. The set of the two-body scattering phase shifts meson-theoretically derived gives a small magnitude of the parameter of optical model potential V_SR. The small value of V_SR is mainly caused by the large positive ³P₀ state phase shift of the two-body scattering. The small value of V_SR gives a small polarization and a small absolute value of the triple scattering parameter for the nucleon scattered from the potential. Furthermore the value of (|V_S| / |V_C|)(\hbar/µc)² calculated by the use of the meson-theoretical phase shifts is smaller than the ones based on the Gammel-Thaler and Signell-Marshak phase shifts. This difference is mainly due to the difference of ³P₀ state phase shifts in the two-body scattering.
