Angular distribution of photoelectron emission as a result of three-photon ionization of Ba atoms
Elizarov A. Yu.
The angular distribution of photoelectrons produced by ionization of Ba atoms was investigated. The atoms were excited into the 6p2(lS0) state of the Ba atom by a two-photon process with linearly polarized dye-laser radiation. This state was ionized by radiation from the same laser. The rotation of the polarization plane of the radiation made it possible to investigate the angular distribution of the photoelectrons for a fixed position of the time-of-flight electron-energy analyzer. The parameter describing the anisotropy of the angular distribution of the emission of photoelectrons was determined by approximating the experimentally obtained angular dependence, which corresponds to the ground state of the ion, of the electronic signal. © 1995 American Institute of Physics.
