Rj. Elliott et al., THE PURE DIAMAGNETIC SPECTRUM OF STRONTIUM, Journal of physics. B, Atomic molecular and optical physics, 29(15), 1996, pp. 3341-3350
We report on one-photon laser spectroscopy experiments in which we hav
e obtained the even z-parity diamagnetic spectrum of Sr by actively ca
ncelling the motional Stark effect. This spectrum differs from previou
s experimental studies in that it contains no electric-field-induced s
tructure. New calculations are reported at a resolution comparable wit
h the experimental data, and an excellent agreement between theory and
experiment is obtained.
