The observation of the pair of Lyman-α and Lyman-β photons produced in the photodissociation of H2

We have measured the coincidence time spectra for the pair of the Lyman-α and Lyman-β photons produced in the photodissociation of H2 in the range of the incident photon energy 32.5 - 42 eV. The result shows that the pair of H(2p) and H(3p) fragments is produced in the photodossociation of H2 molecules.
