The interaction between 14.1 Mev neutrons and Be/sup 9/ was investigated by means of photographic emulsions. The en ergy and angular distributions of neutrons and alpha particles produced in the (n,2n) reaction were measured. The data obtained indicate that the reaction essentially involves a 2.9 Mev excited state in the Be/sup 8/ nucleus (cross section 0.19 plus or minus 0.06 b) and 2.43 Mev excited level in Be/sup 9/. The cross section for excitation of the Be/sup 9/ (2.43 Mev) nucleus and for formation of the ground state in the Be/ sup 9/ nucleus is 0.2 plus or minus 0.1 b. Direct interactions also yield an appreciable contribution to the (n,2n) reaction. The total cross section for the reaction is 0.54 plus or minus 0.07 b. (auth)
