Abstract
The 3He(4He,gamma)7Be reaction plays an important role in determining the high energy solar neutrino flux and in understanding the abundances of primordial 7Li. The present paper reports a new precision measurement of the cross sections of this direct capture reaction, determined by measuring the ensuing 7Be activity in the region of Ec.m.=400 keV to 950 keV. Various recent theoretical fits to our data result in a consistent extrapolated value of S34(0)=0.53(2)(1).Keywords
