Abstract
The astrophysical factor for the proton weak capture on is calculated with correlated hyperspherical harmonic wave functions corresponding to a realistic Hamiltonian consisting of the Argonne two-nucleon and Urbana-IX three-nucleon interactions. The nuclear weak current has vector and axial-vector components with one- and many-body terms. All possible transitions connecting any of the - and -wave channels to are considered. The factor at a center-of-mass energy of is predicted to be , a factor of larger than the value adopted in the standard solar model. The -wave transitions are found to contribute about of the calculated factor.
