Abstract
Resonant excitation to the F1s-sigma* dissociative state in hydrogen fluori de gives a photoelectron spectrum where the spectator part contains strong atomic lines but a participator part where such lines are lacking. We demon strate that this contrasting behaviour between the two parts is due to a st rong dynamical suppression of the resonant contribution, making direct main state photoionization the dominating channel even at resonant conditions.
