Scattering of light ions by /sup 6/Li
The scattering of light ions (n, d, /sup 3/He, and ..cap alpha..) by /sup 6/Li is considered with the single-channel resonating-group method. The cluster internal functions used are translationally invariant shell-model functions of the lowest configurations in harmonic-oscillator wells having different width parameters. The result shows that the essential features of the cross-section angular distributions in all these systems can be reasonably well explained. The use of different width parameters is found to be necessary in the low-energy region where sharp resonance levels exist, but is not essential at higher energies greater than about 10 MeV/nucleon. Effects of nucleon exchanges have also been carefully examined. Here one finds that, even in the present case where a non-closed-shell nucleus is involved, the importance of the core-exchange terms still depends predominantly on the nucleon-number difference of the interacting nuclei. In addition, this investigation shows that the phenomenon of blocking has also a profound influence; it gives rise to a channel-spin dependence for the odd-even phase-shift behavior and may cause a substantial reduction in the effects of core-exchange contributions.
