A recoil separator in combination with a windowless gas target has been designed for the measurement of the radiative capture reaction p(7Be, γ)8B. The separator consists of momentum and velocity filters and a ΔE−E detector telescope. The setup was tested quantitatively using the p(12C, γ)13N reaction at the effective energy Ecm = 841 keV. Projectile fluxes were measured directly with Faraday cups and indirectly with elastic backscattering into Si detectors, while the 13N recoil flux was measured directly with the ΔE−E telescope. A suppression of the 12C beam particles by a factor 2 × 10−10 was observed when the system was tuned for the recoil 13N's. Special emphasis was given to the charge state probabilities of the 13N recoils. Possible improvements of the system for the measurement of other capture reactions are discussed.read more

Standard solar models, with and without helium diffusion and the solar neutrino problem
TL;DR: In this article, Bahcall and Ulrich showed that using helium diffusion increases the predicted neutrino fluxes by about 0.8 SNU, or 11% of the total rate, in the chlorine experiment; by about 3.5 SNU in the gallium experiments; and by about 12% in the Kamiokande and SNO experiments.
