We report extensive new data on the single-colour two-photon optogalvanic spectra of neon in the visible region. The experimental method enables us to record a pure two-photon spectrum in a region which is full of one-photon transitions. A large number of two-photon transitions originating from two metastable 3s(3/2) 2 , 3s'( 1/2 ) 0 states and one non-metastable 3s(3/2) I state of the 2p 5 3s configuration of neon have been recorded and arranged into 19 Rydberg series. The interchannel interactions among the overlapping Rydberg series have been studied using the multichannel quantum defect theory.
