| Research Abstract |
We started a project of neutrino mass spectroscopy by means of the neutrino pair emission from metastable atoms. It is necessary to prepare the initial metastable state rapidly and efficiently. Atomic barium in a heat pipe oven was used as a target. Making use of super-radiance, which is known as a cooperative radiative effect, the population transfer to the matastable state was achieved with the efficiency of 7% and the duration of a few ns.
