Abstract

On the basis of an exact formalism for DWBA methods we calculate the distorting potentials to be used in a standard distorted-wave Born approximation for systems with strongly coupled channels. We examine for a practically useful model some simple approximate treatments through comparisons of the polarization potentials in the case of elastic and inelastic ¹⁶O + ¹⁶O scattering. The adiabatic approximation omitting the radial kinetic energy in the propagator is found to lead to satisfactory agreement with the exact coupled-channel cross sections.

Folding model analysis of <sup>32</sup>S + <sup>32</sup>S elastic scattering at 70, 90, 97.09, 120 and 160 MeV
1987, Nuclear Physics, Section A
Angular distributions for the ³²S(³²S, ³²S) elastic scattering have been measured at 70, 90, 97.09, 120 and 160 MeV incident lab-energies. The data have been analyzed with the folding model, using the M3Y and DDD interactions. A good reproduction of the data is obtained if a renormalization coefficient for the real part of the optical potential is introduced. Moreover the application of the dispersion relation proposed by Mahaux et al. and which uses the imaginary part does not seem to give renormalization coefficients as important as those found in the analysis of the data.
