Abstract

We have observed single photon one-site (K^-2) and two-sites (K^-1K^-1) double K-shell ionization in C₂H ₂n (n=1-3) sequence and in isoelectronic C₂H₂, N₂ and CO molecules. The spectroscopy of K^-1K^-1 states is much more sensitive to the bond length than conventional ESCA spectroscopy based on single K-shell ionization. The mechanism of single photon two-sites is due to a knock-out process in which a primary photoionized 1s electrons eject another 1s electron on the neighbor atom.
