Sm. Kravchenko et al., SEMIMICROSCOPIC CALCULATION OF THE IMAGINARY PART OF THE NUCLEON-NUCLEUS OPTICAL-POTENTIAL, Physics of atomic nuclei, 61(3), 1998, pp. 400-405
The imaginary part of the optical potential involving the rearrangemen
t component is analyzed for the case of generalized effective Skyrme i
nteraction. It is shown that two- and three-body Skyrme forces are not
equivalent in calculating the imaginary part of the optical potential
. The effect of the rearrangement potential on the radial distribution
of the imaginary part of the optical potential is studied by consider
ing the example of elastic neutron scattering by Ca-40 nuclei.
