Outline of Final Research Achievements

We calculated the rate for mu e-> ee reaction in a muonic atom which can occur if the nature violates the lepton flavor. We got a result , for example, that if we prepare 10^17 muons, we can give a similar constraint with mu to 3 e experiment with a muonic uranium. Furthermore we can distinguish the difference among effective actions for lepton flavor violation by observing the correlation between energies and directions of emitted electrons .
