E. Flemming et al., OBSERVATION OF COHERENCE EFFECTS IN THE POLARIZATION OF LYMAN-ALPHA FLUORESCENCE FOLLOWING PHOTODISSOCIATION OF H-2, Physics letters. A, 192(1), 1994, pp. 52-54
The degree of linear polarization of Lyman-alpha fluorescence followin
g photodissociation of H-2 into H(1s) + H(2l) has been measured at dif
ferent excitation energies. The polarization as a function of the exce
ss energy of the photofragments was observed to oscillate between abou
t 0.1 and 0.2, in qualitative agreement with ab initio predictions of
Glass-Maujean and Beswick.
