Rj. Elliott et al., ACTIVE CANCELLATION OF THE MOTIONAL STARK-EFFECT IN THE DIAMAGNETIC SPECTRUM OF BA, Journal of physics. B, Atomic molecular and optical physics, 28(17), 1995, pp. 537-542
We report on experiments in which we have been able to actively cancel
the motional Stark effect and observe pure diamagnetic spectra for th
e barium atom. These differ from those previously reported in that the
y contain no intruding structure. In addition, the sigma(+) and sigma(
-) spectra have been found to be identical.
