| Outline of Final Research Achievements |
In the first project, we have investigated the neutrino reaction on the light nuclei. Under the environment of supernova explosion, we have studied the weak two nucleon fusion to the deuteron and the electron/positron capture on deuteron. We found appreciable contribution of those processes on the neutrino emissivity. We have suggested to include those neutrino reactions of light nuclei in the simulation of supernova explosion.
In the second project we have proposed a new method to extract neutrino energy distribution from the data of neutrino-nucleus reaction. We have shown the neutrino flux can be extracted from the double differential cross section of muon in the inclusive neutrino-nucleus reaction by using the maximum entropy method. The advantage of this approach is that we need not separate each reaction mechanisms, while in the conventional approach one has to go through the model dependent procedure to identify the ideal quasi-free events.
