Charged-particle-producing reactions of 15-MeV neutrons on /sup 51/V and /sup 93/Nb

Cross sections for the (n,xp), (n,d), and (n,x..cap alpha..) reactions for 15-MeV neutrons on /sup 51/V and /sup 93/Nb have been measured with a magnetic quadrupole spectrometer. The importance of the (n,n'p) reaction as a source of protons is examined by comparing these results with those recently obtained for /sup 46/Ti. Good fits to the (n,xp) and (n,x..cap alpha..) energy spectra require contributions from both equilibrium and nonequilibrium reactions, while only the latter appear in the (n,d) spectra. Calculated values for the (n,n'p) and (n,n'..cap alpha..) cross sections agree well with the experimental values. The cross sections are /sup 51/V(n,xp) 91 +- 14 mb, /sup 51/V(n,xd) 7 +- 3 mb, /sup 51/V(n,x..cap alpha..) 17 +- 3 mb, /sup 93/Nb(n,xp) 51 +- 8 mb, /sup 93/Nb(n,xd) 8 +- 3 mb, and /sup 93/Nb(n,x..cap alpha..) 14 +- 3 mb.
