Summary: We report new experimental evidence of a magneto‐galvanic (MG) effect in commercial hollow cathode lamps (HCL). The goal of our investigation is to clarify the role of the neon 2p 5 3s configuration in the formation of the MG signals. Our results eloquently relate the origin of the MG signal in the HCL discharge with the self‐alignment of the 1s 5 metastable state. The observed destruction of the narrow resonance could be explained analogously to the optical depletion (“pumping‐off”) of the 1s 5 metastable state.Comparison of the MG signals from the NeCu (triangles) and the NeCd (circles) lamps investigated here.
