Scientific paper

Experimental efforts by the Lawrence Livermore National Laboratories/Ohio State radioactive ion beam collaboration are described. We are presently focusing on some reactions which are of great importance in the newly proposed inhomogeneous big bang cosmological models. Specifically we are using our system to make beams of (8)Li for measurements of the (8)Li(d,n) (9)Be and (8)Be and (8)Li(alpha,n) (11) B cross sections. These are the key reactions which determine the production of heavy (A greater than 12) elements during the era of big bang nucleosynthesis, and thus the initial composition of stars and subsequent stellar isotope production. Plans for future experiments, including the measurement of the (7)Be(p,gamma) (8)B cross section will be discussed.
