My. Amusia, ON THE MECHANISM OF THE SMOOTH INCREASE OF THE MEAN ION CHARGE IN AR PHOTOIONIZATION NEAR THE K-EDGE, Physics letters. A, 183(2-3), 1993, pp. 201-204
It is demonstrated, that the Auger decay of the virtually created ls v
acancy can explain semi-quantitatively the experimentally observed (by
Doppelfeld et al. [J.Phys. B26 (1993) 445]) increase of the mean char
ge of the ions, produced in the photoionization of Ar close but below
the 1 s threshold.
