摘要: Laser photodetachment electron spectroscopy (LPES) experiments have been performed at the Negative Ion Research Facility University of Nevada, Reno, using a crossed ion-laser beams apparatus to investigate structure and dynamics heavy atomic anions. A small ion accelerator is used produce monoenergetic negatively-charged ions. Ejected electrons (photoelectrons), produced by collision ions with linearly-polarized photons, are collected their kinetic energy measured hemispherical-sector electrostatic analyzer. The resultant photoelectron spectrum determine affinity (EA) several lanthanides, while limits on affinities for others inferred. In addition, angular asymmetry parameters distribution patterns photoelectrons created laser anions, as well spectral dependence those distributions, determined. Electron can offer crucial information regarding electronic structures these represent key models complex systems.
