Abstract

The 7e + p elastic cross section has been measured at the Centre de Recherches du Cyclotron RIB facility at Louvain-la-Neuve in the c.m. energy region from 0.3 to 0.75 MeV by bombarding a proton-rich target with a radioactive 7e beam. The recoil protons have been detected in the angular range θc.m. = 120.2°-131.1° and θc.m. = 156.6°-170.2° using the LEDA system. From a R-matrix analysis of the cross section data, we obtain the energy and the width of the 1 resonance (E = 0.77 MeV). The ℓ = 0 scattering lengths a = 25±9 fm (channel spin I = 1) and a =-7 ± 3 fm (channel spin I = 2) have been deduced. They are compared to values expected from charge-symmetry properties. Implications on the low energy S-factor of the 7e(p,γ)B reaction are discussed.
