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 ‘ mixing due to the diamagnetic interaction is essential for the description of the observed fluorescence yield intensity enhancement
