IBRAHEEM, Awad A. e AL-AMRI, Huda. Analysis of 4,6,8He+208 Pb elastic scattering at E = 22 MeV using various potentials. Rev. mex. fis. [online]. 2022, vol.68, n.5, e51201. Epub 17-Fev-2023. ISSN 0035-001X. https://doi.org/10.31349/revmexfis.68.051201.
Using phenomenological and microscopic potentials, the experimental angular distributions for the 4,6,8He nuclei elastically scattered from a 208Pb target at E tab = 22 MeV are investigated. Both the modified version of CDM3Y6 interaction based on the inclusion of the rearrangement term (RT) and those obtained from the Sao Paulo Potentials are used for the microscopic potentials. The cluster folding potential for 6 He+ 208 Pb is calculated using the triton + triton cluster structure for 6He. This analysis revealed that the real cluster folding potential strength must be reduced by about 90%. Using the extracted potentials, the total reaction cross sections were successfully reproduced.
