Abstract
The absolute cross section σ of the d(7Li, p)8Li reaction near the Ecm= 0.61 MeV resonance has been measured using a 7Li ion beam and a windowless gas target system filled with D2 gas. The proton yield of the reaction and the β-delayed α-activity of the residual nuclides 8Li were observed both concurrently with the elastic scattering yield, relating σ to the Rutherford scattering cross section σR. The resulting values, σ (from p) = 143.6 ± 8.9 mb and σ (from 8Li) = 151 ± 20 mb, lead to a weighted mean value of σ = 153 ± 6 mb (χ2 = 2.26) including all available values and σ = 146 ± 5 mb (χ2 = 0.05) removing some values from the data set. The consequences for the expected flux of high-energy solar neutrinos are discussed.
