  Neutrinos in water can be detected thanks to several reactions. The most
important one is the inverse beta decay $\bar\nu_{e}+p \rightarrow n+e^{+}$ .
The detection of 2.2 MeV from neutron capture on free protons is very
difficult. The feasibility of Gadolinium (Gd) doping in water Cherenkov
detectors essentially reduces background signals and enhances the sensitivity
to neutrino detection. In this work, the supernova neutrino charged-current
interactions with the most abundant Gd even isotopes (A=156,158 and 160) are
studied. We use measured spectra and the quasiparticle random phase
approximation to calculate the charged current response of Gd isotopes to
supernova neutrinos. Flux-averaged cross sections are obtained considering
quasi-thermal neutrino spectra.
