Abstract

The absolute cross sections for the formation of the H(2s) and H(2p) atoms, σ2s and σ2p, respectively, in photoexcitation of CH4 and NH3 were measured in the range of the incident photon energy 15-48 eV for studying superexcited states of the molecules. The same superexcited states were found to contribute to the σ2s and σ2p cross sections. It was concluded that the non-adiabatic transitions play a significant role during the dissociation of the superexcited states and ionic states.
