Angular correlation measurements of a pair of Lyman-α photons emitted in the photodissociation of H2

The angular correlation functions of a pair of Lyman-α photons in the photodissociation of H2 are measured more precisely than in the early experiments [Nakanishi et. al., Phys. Rev. A. 90, 043405(2014)]. The linearly polarized light is used to excite the photodissociation via the doubly excited Q2 1Πu(1) state.
