Cross sections of the Ni-58(n,p)Co-58, Co-59(n,p)Fe-59, V-51(n,alpha)S
c-48, and Co-59(n,2n)Co-58 reactions actions and isomer ratios for the
Ni-58(n,p)Co-58 reaction were measured for some neutron energies betw
een 9 and 14 MeV. Neutron spectrometry, with an NE-213 scintillation d
etector, of the beams from the D(d,n)He-3 reaction was used to evaluat
e the activation induced by breakup neutrons on natural nickel, cobalt
, vanadium, and aluminum-monitor targets. The results are compared wit
h earlier measurements and with theoretical calculations performed wit
h the aid of the GNASH code (Hauser-Feschbach model including pre-equi
librium corrections).
