Abstract
Intensity beats in the emission of from beam-foil excited hydrogen in various static electromagnetic field configurations have been studied. The observed beat frequencies agree with the calculated values, which are independent of the field directions. The beat amplitudes, however, show significant dependence on the field directions relative to the beam. The theory for emission of light from the decay of coherently excited states is applied in the sudden perturbation limit. Agreement with experiment can only be obtained under the assumption that the foil excitation generates initial coherent wave functions , where notation and the beam as quantization axis are used. The ratio is then determined, which gives the ratio of the excitation cross section of the to that of the states as at a beam energy of 200 (keV) per atom.
