Proton capture cross section of 7Be and the flux of high energy solar neutrinos

Le résumé fourni par la source

The low energy cross section for the 7 Beip, γ ) 8 B reaction has been measured by detecting the delayed α particles from the 8 B beta decay. Detailed d-scussion is presented of the analysis of the radioactive 7 Be target including the use of two independent methods to determine the 7 Be areal density. The direct capture part of the cross section is subtracted from the total cross section to deduce resonance parameters for the 1 + first excited state in 8 B. The zero-energy astrophysical 5 factor inferred from the present experiment is compared with previous values. The effect on the 37 Cl solar neutrino capture rate, predicted by the standard solar model, is also discussed.
