Measurement of the solar neutrino interaction rate below 3.49 MeV in Super-Kamiokande-IV

Kamiokande Collaboration, A. Yankelevich, K. Abe +250

Super-Kamiokande (SK) has observed ${}^8\text{B}$ solar neutrino elastic scattering at recoil electron kinetic energies ($E_{\text{kin}}$) as low as 3.49 MeV to study neutrino flav…
