Absolute cross sections for 7.8-Mev deuterons were measured for the following reactions: Zr/sup 94/(d alpha )Y/sup 92*/. Zr/sup 92/(d, alpha )Y/sup 90*/; Zr/sup 90/(d, alpha )Y/sup 88*/; Mo/sup 9/ s/sup 7/(d, alpha )Nb/sup 95*/: Mo/sup 97/(d alpha )Nb/sup 95/m; Mo/sup 98/(d, alpha )Nb/sup 96/; Mo/sup 92/(d, alpha )Nb/sup 90/; Ti/sup 46/(d , alpha )Sc/sup 44/; Ti/sup 48/(d, alpha )SC/sup 46/; and S/sup 34/(d, alpha )P/sup 32*/. Excitation functions were determined for the reactions indicated with an asterisk. Beam intensity was determined with a Faraday cage coupled to a current integrator able to measure the current with less than 1% error. The reaction products from the thin targets were chemically purified by carrier-free separations. The absolute disintegration rates were determined by 4 pi beta counting and coincidence gamma counting. Carrier- free tracer techniques were used to establish the yields of chemical purification steps. (auth)
