5. Magnetic-field induced enhancement in the fluorescence yield spectrum of doubly excited states in helium.

Abstract

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

6. Double excitations of helium in weak static electric fields.

Author

Såthe C, Ström M, Agåker M, Söderström J, Rubensson JE, Richter R, Alagia M, Stranges S, Gorczyca TW, and Robicheaux F

Abstract

A dramatic electric field dependence has been observed in the fluorescence yield spectrum of the doubly excited states in helium, where a rich phenomenology is encountered below the threshold. Fluorescence yields of certain states can be tuned to zero, while other dipole-forbidden states are significantly enhanced, for fields much weaker than 1 kV/cm. Using an R-matrix multichannel quantum defect theory, spherical-to-parabolic frame transformation method, we are able to reproduce the main features of the observed spectrum, and we discuss the qualitative behavior in terms of weak electric field mixing.
