Abstract

The present paper reports a new precision measurement of the cross sections of the direct capture reaction3He(4He, γ)7Be in the region of Ec.m.= 400 keV to 950 keV by measuring the ensuing7Be activity. This reaction plays an important role in determining the high energy solar neutrino flux and in understanding the abundances of primordial7Li. Various recent theoretical models are fitted to obtain a consistent extrapolated value of S34(0) = 0.53(2)(1) keV-b. © 2005 Elsevier B.V. All rights reserved.
