Double Auger Probabilities from Xe4dj, Kr3dj, and Ar2pjHole States

The yield ratios of triply charged ions to doubly charged ions produced from Xe + with 4 d 3/2 and 4 d 5/2 holes, from Kr + with 3 d 3/2 and 3 d 5/2 holes, and from Ar + with 2 p 3/2 and 2 p 1/2 holes have been measured using a coincidence technique between an energy-selected photoelectron and a charge-specified ion. The difference in the ratios of the double to the normal Auger transitions from the 2 p 3/2 and 2 p 1/2 hole states in Ar + and that in the ratios from the 3 d 5/2 and 3 d 3/2 hole states in Kr + are small. However the difference in those from the 4 d 5/2 and 4 d 3/2 hole states in Xe + is significant. This difference probably originates from the fact that the energy of the ground state of Xe 3+ is just below that of the 4 d 5/2 hole state of Xe + , i.e., the difference in the excess energy and the number of available states play a critical role in the transition.
