Effects of a revised ^7^Be e^-^-capture rate

Theoretical evaluations have to account for not only the nuclear interaction, but also the processes in the plasma where ^7^Be ions and electrons interact. In the past decades several estimates were presented, pointing out that the theoretical uncertainty in the rate is in general of few percents.

In the framework of fundamental solar physics, we consider here a recent evaluation for the ^7^Be+e^-^ rate, not used up to now in the estimate of neutrino fluxes. We analysed the effects of the new assumptions on Standard Solar Models (SSMs) and compared the results obtained by adopting the revised ^7^Be+e^-^ rate to those obtained by the one reported in a widely used compilation of reaction rates (ADE11). We found that new SSMs yield a maximum difference in the efficiency of the ^7^Be channel of about -4% with respect to what is obtained with the previously adopted rate.
