“…This effect has been revealed by using linearly polarized light, first in experiments performed with angular selectivity [17][18][19] or, more recently, with full angular resolution [20]. The experimental Doppler profiles of the fragment lines may serve as a fingerprint of nuclear dynamics [8,14] and are widely used in investigations of ultrafast dissociation processes in core-excited states [8,9,15,[17][18][19][20][21][22][23][24][25].…”
