Comment on “Influence of protons on the capture of electrons by ${}^7\mathrm{Be}$ in the Sun”

This paper suffers from conceptual difficulties and unjustified approximations that render its conclusions invalid. The influence of protons on electron capture by ${}^7\mathrm{Be}$ in the Sun is already included in the standard plasma screening correction to the density of thermal electrons at the ${}^7\mathrm{Be}$ nucleus needed for calculating the capture rate. Moreover, the approximation to the three-body wave function that underlies the entire argument of Belyaev, Tater, and Truhlík [Phys. Rev. C 75, 034608 (2007)] is not valid in the limit under consideration, namely when the electron and the ${}^7\mathrm{Be}$ nucleus are spatially coincident and the proton is some 30 000 fm away from the other two particles.
