Abstract

The [Formula presented] reaction plays a central role in the evaluation of solar neutrino fluxes. We report on a new precision measurement of the cross section of this reaction, following our previous experiment with an implanted [Formula presented] target, a raster-scanned beam, and the elimination of the backscattering loss. The new measurement incorporates a more abundant [Formula presented] target and a number of improvements in design and procedure. The point at [Formula presented] was measured several times under varying experimental conditions, yielding a value of [Formula presented]. Measurements were carried out at lower energies as well. Because of the precise knowledge of the implanted [Formula presented] density profile, it was possible to reconstitute both the off- and on-resonance parts of the cross section and to obtain from the entire set of measurements an extrapolated value of [Formula presented].
