چکیده انگلیسی
We have studied the excitation and relaxation of Ar+ ions populated in resonant Auger decay from the Ar 2pâ1nl core-excited states by using ultraviolet-visible fluorescence spectroscopy and photon-photon delayed coincidence technique. Fluorescence emission yields were measured in the photon energy range of 240--255â¯eV for the 3s23p4(1D)5s(2D) â 3s23p4(1D)4p(2F) (393â¯nm) and 3s23p4(1D)4d(2F) â 3s23p4(1D)4p(2F) (335â¯nm) transitions as well as for the 380-500â¯nm wideband emission. Delayed coincidence photon decay curves for the cascade transitions of the 335/459 nm and 393/459 nm lines were measured at the four most intense Ar 2p core excitations and the coincidence yields for both studied cascade channels were obtained at these Ar 2p excitations.
