Abstract

We report the observation of magneto-galvanic resonances (MGR) in traditional galvanic detectors--Ne-Cu (`Narva' type) and Ne-As (Pye Unicam) hollow-cathode lamps (HCL). We carried out comparative investigations of the characteristics of the MGR and the laser-induced galvanic signals arising as a result of the irradiation of the HCL by different laser lines. We believe that the variation of the discharge conductivity is caused by the self-alignment of the 1s₅ Ne metastable state. We also discuss some of the possible mechanisms that may relate the self-alignment destruction to the discharge conductivity change.
