Abstract

Using neutrons from the Li7(p,n)Be7 reaction, the cross sections for the reactions N14(n,p)C14 and N14(n,α)B11 were measured for neutron energies from 150 to 2100 kev. Resonances for the (n,p) reaction were found at 499, 640, 993, and 1415 kev; for the (n,α) reaction at 1415 and 1800 kev. Information was obtained about the excited state of Be7. It was found to lie 431±5 kev above the ground state, and probabilities for its formation in the Li(p,n) reaction were determined.
