Outline of Final Research Achievements

A pair of H(2p) atoms produced in the photodissociation of H2 is potentially entangled. The promotion of the fluorescence emission from 2p to 1s state was pointed out from the time difference measurements of the pair of photons. The purpose in this work was to clarify the mechanism of the promotion of the fluorescence emission.
However, with improvement of the quality of measurements, we have noticed that our coincidence signals were contaminated by the unexpected false coincidences originated from cosmic muons. The promotion of the fluorescence emission was not reproduced under the more confidential conditions.
