✦ Synopsis

The production of 75Br by the 78Kr (d,n alpha)75Br reaction using a 21.5 MeV deuteron beam was investigated. With our 78Kr gas target, the production yield was found to be 5.9 +/- 0.9 mCi/microA at saturation. The major impurities in the 75Br product were 76Br and 77Br which amounted to about 6 and 2.5% respectively, at EOB. Sufficient amounts of 75Br could easily be prepared by this method for use in chemistry and animal experiments but deuteron energies greater than 20 MeV are required.

Excitation functions were measured for 'sKr(p,pn)"Kr, 'sKr(p,x)"Br and 7\*Kr(p,a)75Br reactions from threshold to 20 MeV by the activation technique using 99.4% enriched 78Kr as target gas. There is a strong discrepancy between our data and the literature values for the 78Kr(p,pn)77Kr and 78Kr(p,a)'
