Main points on which this project work give focuses are the interaction of neutrino with matter, neutrino reaction cross section, mean free path of neutrino, neutrino helicity and experimental measurement of helicity. Experimental detection of neutrino will be descussed on the basis of cowan and F. Rein's experimentenNeutrinoThesis
