Research Abstract

It was predicted by our group that the pair of H(2p) atoms following the photodissociation of molecular hydrogen is entangled. In the present study we aim at examining the prediction, determining the entangled state of H(2p) atoms and investigating the dynamics of the entangled atom-pair. The entanglement in the atom-pair is copied to the photon-pair. By using the new apparatus, in which two photon-detectors are rotated independently along the incident light beam, the angular-correlation and time-correlation functions of the pair of the Lyman-alpha photons have been measured in the extensive range of pressures and compared with the theoretical prediction. It has turned out that the magnetic quantum number of at least one hydrogen atom in the pair is not definite.
