V51(p, n)Cr51Reaction as a 5- to 120-kev Neutron Source

The ${\mathrm{V}}^{51}(p, n){\mathrm{Cr}}^{51}$ reaction provides a usable source of monoenergetic neutrons from 5 to 120 kev. The yield indicates resonances in ${\mathrm{Cr}}^{52}$ with an average spacing of less than 2 kev in this evergy range. A preliminary measurement was made of the angular distribution of eleven of the more prominent peaks.
