| Research Abstract |
Method for analyzing the neutrino from the sun which penetrates the moon is established. Neutrino interacts with matter extremely weakly and it is hard to control. Our project uses coherent interaction of the neutrino with matter. The coherent interaction of the neutrino with the Moon makes the phase shift to be about pi and is used. For the practical purpose of Moon analysis, however, the present neutrino detector is not sufficient due to the short period of eclipse, i.e., a few minutes. So better detector with high efficiency of detection is necessary.
