Analysis of Angular Distributions of Heavy-ion Transfer Reactions

Proceeding as in our earlier analysis of elastic scattering, but with a form for the S matrix appropriate for transfer, peaked at the critical value Ie and with width parameter .d, it is shown how to analyse the angular distribution of transfer reactions of heavy ions to obtain.d. The effect of the nuclear phases is found not to be of such fundamental importance as in elastic scattering. Analysis of theexperimental data reveals an increase of.d with nuclear size especially at low energies, but an increase of nuclear penetration for transfer collisions of the lightest nuclei. The circumstances in which strong coupling might occur between elastic scattering and transfer are examined.

Nuclear Phases

Taking the magnitude of the elements of the S matrix and the nuclear phases to be of Woods-Saxon form in the variable I with width parameter LI, we find that the form of the scattering amplitude components f+(B) and f-(B) is specified by the parameters LI+ and LI- such that LI is closely the geometric mean of LI+ and LI-. Many angular distributions have been analysed into f+(B) and f-(B) to obtain LI+ and LI- and hence LI, the angular momentum diffuseness, from which the nuclear surface diffuseness is obtained, so reducing an ambiguity in the nuclear potential. The case of light ions incident on heavy ions has also been investigated.

Nuclear Excitation

The relative contributions of nuclear and Coulomb excitation to inelastic collisions of heavy ions are examined, and it is shown how to distinguish their effects on the angular distribution. From the experimental distributions for Coulomb excitation it is possible to make an estimate of the effective range of the Coulomb interaction in the collision. The distributions for nuclear excitation are analysed in the same way as in our previous work on transfer reactions, and give very similar results for the greater nuclear penetration in such collisions as compared with elastic collisions.

Preliminary Study

Optical model analyses of elastic scattering of heavy ions have been carried out by Porter (1958) for nitrogen-nitrogen, and a preliminary study of the carbonnitrogen system has been made by Bassel, Melkanoff, and Drisko (Halbert, Hunting, and Zucker 1960). These analyses have shown that the optical model is capable of predicting, to a higher accuracy than the semiclassical models, the heavy ion elastic angular distributions.
