Competition between autoionization and radiative emission in the decay of excited states of the oxygen atom
High resolution relative photoionization cross sections are reported for a number of autoionizing states of atomic oxygen, including the metastable 3s 3P0, and 2s2p5 3P0 states. The wavelength resolut...

Electronic oscillator strengths for induced dipole transitions in alkali–rare gas systems have been calculated as a function of internuclear distance using adiabatic potential energy curves and molecular wavefunctions previously obtained from a pseudopotential model. The molecular transitions considered are those associated, in the separated atom limit, with S–S and S–D electric dipole forbidden transitions in the alkali atom. The oscillator strengths are found to be relatively large (about 10−2–10−4) at small and intermediate internuclear distances (R~3–12 a.u.).
