  In this paper we consider high-intensity source of electron antineutrinos
from the production and subsequent decay of 8Li. It opens a wide range of
possible searches for beyond standard model physics via studies of the inverse
beta decay interaction. In IsoDAR experiments Lithium 8 is a short lived beta
emitter producing a high intensity anti-neutrinos, which is very suitable for
making several important neutrino experiments. In this paper we used the GEANT4
program. to simulate neutrino production using proton and deuteron beams. We
find that the neutrino production rate is about 3 times from deuteron beam than
from proton beam in low energy region.
