Fe+ in its Ground 6D State: A Direct Measurement of the J = 1/2 -3/2 and J = 3/2 - 5/2 Fine-Structure Intervals
J M. Brown, H Korsgen, K M. Evenson
The J = 1/2 <- 3/2 and 3/2 <- 5/2 fine structure transitions in the atomic ion Fe+ in its ground 6D state have been detected in the laboratory by far-infrared laser magnetic resonance at 87 and 51 υm. The fine-structure intervals have been measured accurately by extrapolation to zero magnetic field as 3430.7762 (19) and 5843.7984 (12) GHz, respectively.
