Cross sections for the formation of H(2p) atom via doubly excited states in photoexcitation of rotationally cold H2

Cross sections for the formation of H(2p) atom in photoexcitation were measured for H2 in the lowest rotational level in the energy range of the doubly excited states for examining contribution of the non-adiabatic transition between the 1Σ u − 1Π u doubly excited states.
