Outline of Final Research Achievements

Radiative emission of neutrino pair (RENP) from atoms or molecules has been considered a novel tool to determine the yet unknown neutrino parameters. In order for a future RENP experiment, (1) we proceeded detail study of macro-coherent amplification mechanism for developing an experimental method to control higher order  process of quantum electrodynamics such as two-photon paired superradiance or multiphoton emission; (2) search the best target that has high-density and long coherence time for RENP process. We have succeeded to enhance the emission rate to 18 orders of magnitude in the two-photon emission process by optimizing the experimental parameters. Also we have observed automatic development of coherence in the solid parahydrogen crystal. The coherence seems to increase 10 times longer time duration than the input pulse duration. We developed the excitation laser for Xe gas, which is a suitable candidate for the RENP experiment.
