The Disintegration of Lithium by Deuteron Bombardment

Thin target excitation curves for the Li⁷(d,n), Li⁶(d,n), and Li⁷(d,p) reactions are presented. The neutron data were taken at 90^∘{} to the deuteron beam using a BF₃-filled proportional counter in the long geometry. Resonances were observed in the Li⁶(d,n) reaction at 0.41 and at 2.12 Mev, in the Li⁷(d,n) reaction at 0.68, 0.98, and 2.1 Mev, and in the Li⁷(d,p) reaction at 0.75, 1.00, and 1.4 Mev. These resonances correspond to excited states in Be⁸ at 22.58 and 23.86 Mev and in Be⁹ at 17.22, 17.45, 17.8, and 18.3 Mev. The cross section of the resonances observed in the Li⁶(d,n) reactions were 9 and 41 millibarns/steradian, those for the Li⁷(d,n) reaction were 39, 43, and 58 millibarns/steradian, and those for the Li⁷(d,p) reaction were 0.230, 0.235, and 0.255 barn.
