Abstract
The angular distribution of two Lyman- photons, i.e., the probability density that two Lyman- photons are emitted in given directions, in the photodissociation of a hydrogen molecule have been measured at the hydrogen gas pressures of 0.40 and 0.13 Pa. We have found that the experimental angular distributions seem to approach the theoretical one by our group [J. Phys. B 40, 617 (2007)] with decreasing pressure, which indicates the generation of the entangled pair of atoms shown in the theory and the role of the reaction of the entangled pair of atoms with an molecule that efficiently changes the entanglement.
