Abstract
We describe a new experiment dealing with the multiphoton ionization o f metastable atomic hydrogen H(2s). The ion yield has been measured in a relative way but it provides absolute photoionization rates. In the present contribution, the wavelength is tuned in the vicinity of the 2s-3p transition and the laser intensity is in the 10(7)-5 x 10(10) W cm(-2) range. Experimental photoionization rates and resonance width a re found to be in agreement with theoretical predictions.
