摘要
Elastic, inelastic scattering as well as one-neutron transfer channels have been measured over a wide angular range for systems O-16 + O-16 at the incident energy of 350 MeV and Ne-20 + C-12 at 390 MeV, respectively, using the Q3D magnetic spectrometer. In both cases differential cross sections have been measured down to about 50 nb/sr (or dsigma/dsigma(R) less-than-or-equal-to 10(-4)) at large angles. For the O-16 + O-16 system refractive contributions are found at the level of these cross sections, whereas in the Ne-20 + C-12 case a steeper decrease of the differential cross section with the angle is observed and the refractive contribution can not be determined. The elastic scattering data have been analyzed using standard Woods-Saxon potentials and potentials calculated in different versions of the double-folding model. Some properties of these potentials are tested in the calculations for inelastic scattering and one-neutron transfer within the DWBA. With the refractive pattern observed for the O-16 + O-16 system, the scattering and transfer data are found to be sensitive to the interaction potential at small internuclear distances down to about 2.5 fm.
