Extended Data Table 1 Isotope shifts of argon isotopes relative to 38Ar on the 811.8 nm cooling transition

From: Detection of atmospheric 42Ar at the 10−21 level by atom counting

  1. The isotope shifts of 40Ar, 39Ar, and 36Ar are taken from existing spectroscopy data23. The isotopic shift of 42Ar is measured in this work. Values in parentheses indicate one standard deviation. a Results from Reference23. b Measured in this work.
