Nuclear interactions of low energy lithium ions
Abstract
Elastic scattering Li-8 + Li-8 and Li-7 was studied for E sub b/ =2.0 to 5.5 MeV. A double folding optical potential model provided a good fit to the data for Li-7 + Li-7, over the entire energy range and for Li-6 + Li-6 with energies low enough so that the breakup Li-6 yields alpha + d does not occur. At higher energies, the potential falls off rapidly. At 5.5 MeV the potential well was 36% as deep as was predicted by the folding model. The 2.0 MeV double folded potential allowed a magnificent fit to the experimental data when the 2Li-6 yields 3 alpha reaction was used in a DWBA calculation. The total cross section for producing a neutron from Li-7 + Li-7 was measured for a number of energies. These cross sections compare favorably with the total reaction cross section calculated from the partial wave amplitudes generated from the folding model potentials. The cross sections were large. The cross section at E sub b = 4.0 MeV was 0.475 b.
