MAHMOUD, Zakaria M. M.. Microscopic spin orbit analysis for proton+⁹Be scattering. Rev. mex. fis. [online]. 2022, vol.68, n.3, e031203.  Epub Apr 14, 2023. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.68.031203.

We simultaneously reanalyzed the elastic scattering differential cross-sections (dσ/dΩ) and the vector analyzing power (Ay ) of p+9Be system. This analysis was performed using microscopic folded potentials for both the real central and the spin-orbit. For the imaginary central, we used surface Woods-Saxon (WS) potential. We aimed to test the microscopic spin orbit potential based on the M3Y effective nucleon-nucleon interaction for the light system p+9Be. The present calculation showed that the microscopic spin orbit potential satisfactory reproduce A y above 8 MeV and qualitatively reproduced Ay below 8 MeV. In addition, we found that the calculated real central potentials successfully reproduced the dσ/dΩ for all the considered energies. From the present analysis, we excepted that the present microscopic spin orbit potential could reproduce successfully the Ay for p+nucleus as the incident proton energy increases above 10 MeV.
