ELASTIC SCATTERING OF HE-3 PARTICLES AT 450 MEV

摘要

Elastic scattering of He-3 particles from C-12, Si-28, Ni-58, Zr-90 and Pb-208 was measured at an incident energy of 450 MeV. Data were analyzed in the framework of the optical model based upon the Woods-Saxon parametrization. The depth of the real potential was determined to be about 30 MeV, irrespective of the target nucleus. It was found that volume integrals per nucleon of the real potentials became close to that of the proton and those of the imaginary potentials were about one half of that of the proton. A new empirical formula is proposed regarding the volume integrals per nucleon of the imaginary potentials. [References: 23]
