abstract = {We report on an improved measurement of the 8B solar
neutrino interaction rate with the Borexino experiment at
the Laboratori Nazionali del Gran Sasso. Neutrinos are
detected via their elastic scattering on electrons in a
large volume of liquid scintillator. The measured rate of
scattered electrons above 3 MeV of energy is
0.223+0.015−0.016(stat)+0.006−0.006(syst) cpd/100 t,
which corresponds to an observed solar neutrino flux
assuming no neutrino flavor conversion of
$Φ^{ES}_{8B}=2.57+0.17−0.18(stat)+0.07−0.07(syst)×10^6$
cm−2s−1. This measurement exploits the active volume of
the detector in almost its entirety for the first time, and
takes advantage of a reduced radioactive background
following the 2011 scintillator purification campaign and of
novel analysis tools providing a more precise modeling of
the background. Additionally, we set a new limit on the
interaction rate of solar hep neutrinos, searched via their
elastic scattering on electrons as well as their neutral
current-mediated inelastic scattering on carbon,
12C(ν,ν′) 12C* (Eγ= 15.1 MeV).},
