Production of /sup 91/Nb, /sup 94/Nb, and /sup 95/Nb from Mo by 14. 5--14. 8 MeV neutrons

Journal Article · · Phys. Rev. C; (United States)
Production cross sections for /sup 94/Nb(2.03 x 10/sup 4/ yr) have been measured from enriched /sup 94/Mo and /sup nat/Mo. The samples were irradiated by 14.5--14.8 MeV neutrons and the cross sections were measured by gamma spectroscopy. The cross section for the /sup 95/Mo(n,np+d)/sup 94/Nb reaction was deduced from the difference in /sup 94/Nb activity in the natural and enriched Mo samples. Cross sections were also determined for the /sup 95/Mo(n,p)/sup 95/Nb, /sup 92/Mo(n,x)/sup 91/Nb/sup m/, and /sup 98/Mo(n,..cap alpha..)/sup 95/Zr reactions, all being in good agreement with previous data. Our data can also be used to estimate the production of the long-lived (700 yr) ground state of /sup 91/Nb/sup g/ from /sup 92/Mo.
