Outline of Final Research Achievements

This research titled“Searching for the electron's EDM by using a radical molecule in para hydrogen crystal as a magnetic sensor”has performed to establish a new experimental approach for the detection of eEDM by using polar molecular radical in the p-H2 crystal. As the result, we established to generate a certain mount of HgH radicals in the crystal, which is one of the promising candidate molecules for the eEDM experiment. Another result is an establishment of monitoring the orientation of a polar molecule in the p-H2 crystal by using IR polarization laser spectroscopy. From this work, we found that the orientation of CH3F molecule is not along the crystal c-axis but tilted 64.5 degree from it.
