Elastic Scattering of Protons from Cu⁶³ and Cu⁶⁵ in the Energy Range from 7.54 MeV to 14.64 MeV

抄録

Energy dependence of the elastic scattering of protons from Cu⁶³ and Cu⁶⁵ were investigated between 7.5 MeV and 14.6 MeV. At four angles of 30°, 60°, 95° and 165°, differential cross sections were measured at about every 200 keV and angular distributions were also observed at every 800 keV for both isotopes. The observed angular distributions showed the typical diffraction patterns. An optical model analysis was made for every angular distribution and the parameters of the optical potentials were obtained as functions of incident energies.
