Calculation of the 6He + p elastic scattering cross sections within the folding approach and the high-energy approximation for the optical potential (original) (raw)

Calculations of microscopic optical potentials (OP's) (the real and imaginary parts) are performed to analyze the 6 He+p elastic scattering data at tens of MeV/nucleon (MeV/N). The OP's were constructed on the basis of two microscopic models (the folding procedure and the high-energy approximation) using three model densities of 6 He. Cross sections were calculated with a help of DWUCK4 code. The effect on cross sections of the dependence of the NN-forces on nuclear matter density is investigated. The role of the spinorbital terms and the non-linearity of the OP's and also the role of its renormalization are studied. The sensitivity of the cross sections to these effects is tested.
