Following our initial production of beams of /sup 7/Be and /sup 13/N, we have improved the purity and intensity of these beams. In addition we have generated beams of /sup 15/O (at 30 MeV) and /sup 8/Li (at 22 MeV). These beams are intended for cross section measurements of proton and alpha-particle capture reactions on unstable species that are important in hot stellar environments. We have begun studies aimed toward measuring the /sup 1/H(/sup 7/Be,/sup 8/B)..gamma.. cross section. As part of the developmental work, we attempted to remeasure the /sup 2/H(/sup 7/Be,/sup 8/B)n cross section with a different technique that pointed out the importance of background /sup 8/Li. We measured the /sup 2/H(/sup 7/Li,/sup 8/Li)/sup 1/H cross section to be 155 +- 20 mb at 12.2 +- 1.3 MeV.
