Research Abstract

The eigen states whose energy separation is smaller than the life time broadening has been considered to be inseparable with conventional high-precision spectroscopies. The purpose of this work is the development of the conceptually new spectroscopy to resolve these states with applying wavepacket interferometry to short lived electronically excited states. Though the high precision interferometer for the demonstration has been constructed, actual tests have not been executed because I have changed the institute. Then, more efficient systems for the demonstration have been searched with a theoretical collaborator.
