Laser-magnetic-resonance detection of magnesium atoms in the metastable /sup 3/P/sub 0,ts1,ts2/ states
Transitions between fine-structure levels of the metastable (3s3p/sup 3/P) state of magnesium have been observed by means of the highly sensitive technique of far-infrared laser-magnetic-resonance spectroscopy. The g factors for the /sup 3/P/sub 1/ and /sup 3/P/sub 2/ levels are 1.50111(16) and 1.50102(16), respectively, and the /sup 3/P/sub 1/--/sup 3/P/sub 2/ energy separation is1 220575.1(33) MHz. The observed g factors show good agreement with the predicted values. This stands in marked contrast to similar results for atomic silicon (/sup 3/P) and aluminum (/sup 2/P), for which the theoretical and experimental g factors differ substantially. The value of the /sup 3/P/sub 1/--/sup 3/P/sub 2/ energy separation is improved by nearly 2 orders of magnitude over the optical value and is of sufficient accuracy to permit possible extraterrestrial identification.
