Abstract
The use of a threshold photoelectron/photoion coincidence spectrometer for the study of threshold photodouble ionization processes is descri bed. This spectrometer has been used to determine the value of the exp onent a in the Wannier law and its range of validity, and to investiga te the behaviour of the asymmetry parameter beta for near-threshold ph otoionization. The experimental results are compared with theoretical predictions.
