ANOMALOUS MAGNETO-OPTICAL RESONANCES ON THE 2p<sup>5</sup>3s STATES IN A Ne DISCHARGE

Abstract

Magneto-optical resonances (MOR) have been experimentally observed, resulting from destruction of the self-alignment of the resonant - 3 P 1 (1s 4 ), and the metastable 3 P 0 (1s 3 ), 3 P 2 (1s 5 ) levels of NeI . The most surprising results have been observed at the lines 616.3 and 626.6 nm. The absorbing level 3 P 0 (1s 3 ) has a g-factor J = 0; thus no MO Faraday signal from this level should be expected. Besides, MO signals for the 585.2 nm line have not been observed. From the level 1s 5 , two-component signals have been registered. A model describing the behavior of the MOR observed at the 2p 5 3s Ne level will be discussed.
