摘要
An influence of static magnetic fields on the fluorescence yield spectrum of He in the vicinity of the N=2 thresholds has been observed. The experimental results are in excellent agreement with predictions based on multichannel quantum defect theory, and it is demonstrated that the Rydberg electron center dot mixing due to the diamagnetic interaction is essential for the description of the observed fluorescence yield intensity enhancement.
