Single-photon multiple ionization of the argon dimer van der Waals complex, Ar-2, is studied by the photoelectron-photoion-photoion coincidence technique using synchrotron radiation in the photon-energy range of 255-340 eV, which covers the Ar 2p and Ar 2s ionization continua. Dissociation processes into Ar+ + Ar+, Ar+ + Ar2+, Ar+ + Ar3+, and Ar2+ + Ar2+ ion pair channels are observed. The Ar+ + Ar+ and Ar+ + Ar2+ channels show the most intense ion-ion coincidences, compared to other observed dissociative channels. For the four observed channels the intensities are integrated and compared as functions of photon energy.

Abstract
Single-photon multiple ionization of the argon dimer van der Waals complex, Ar-2, is studied by the photoelectron-photoion-photoion coincidence technique using synchrotron radiation in the photon-energy range of 255-340 eV, which covers the Ar 2p and Ar 2s ionization continua. Dissociation processes into Ar+ + Ar+, Ar+ + Ar2+, Ar+ + Ar3+, and Ar2+ + Ar2+ ion pair channels are observed. The Ar+ + Ar+ and Ar+ + Ar2+ channels show the most intense ion-ion coincidences, compared to other observed dissociative channels. For the four observed channels the intensities are integrated and compared as functions of photon energy.File in questo prodotto:
