| Abstract: | The elastic scattering of 6Li + 16O at 48 MeV has been measured and fitted with an optical model calculation. Measurements have been made of the 16O(6Li, α)F reaction at 48 MeV populating the 1+ g.s., 3+ 0.927 MeV and 5+ 1.122 MeV states in 18F. The data exhibit cross sections at large angles comparable to those at forward angles, and have been compared with exact finite-range DWBA calculations. Exchange contributions were included for the 1+ g.s. and were unable to account for the large-angle data. Calculated statistical compound nucleus cross sections were approximately a factor of 100 below the data. The same conclusions are reached for previously published data at 34 MeV. |
