Simultaneous determination of radiative and nonradiative decay channels inthe neon K shell - art. no. 014702

The photoelectron-photoion coincidence method is shown to be very successfu l for the quantitative investigation of the ratio of radiative to nonradiat ive transitions and for the ratio of single to double Anger transitions. Th ese decay probabilities are important parameters for analytical methods as well as for theoretical descriptions. The method is demonstrated for the ne on 1s decay. Especially the fluorescence yield ana the yield for the double Auger process have been determined both experimentally and theoretically.
