A measurement of the (n,t) cross sections for Beg/sup 9/, B/sup 10/, and B/sup 11/ is described. The tritium yield was determined by absolulte counting of the beta activity. Neutron fluxes were measured by standard techniques. The following values were obtained for the (n,t) cross sections at the indicated neutron energies: Be/sup 9/ at 14.1 Mev. 18 plus or minus 1.5 mb: B/sup 10/ at 4 Mev. 95 plus or minus 10 mb: B/sup 10/ at 5.6 Mev. 230 plus or minus 25 mb: B/sup 10/ at 9.6 Mev. 125 plus or minus 15 mb: B/sup 10/ at 14.1 Mev. 85 plus or minus 6 mb: B/sup 10/ for fission spectrum. 30 plus or minus 2 mb; B/ sup 11/ at 14.1 Mev, l5 plus or minus 5 mb.
