We respond here to the criticisms raised by Klapdor-Kleingrothaus and his colleagues, and re-establish that our result is based on very conservative premises and that the "indication of a signal of 1.4 $σ$" for the decay of the electron in the $γ+ν$ channel, reported by Klapdor-Kleingrothaus and colleagues, is excluded by the Borexino result.6 pagesHigh Energy Physics - Experimenttext
