Oscillator strengths for S–S and S–D induced dipole transitions in alkali–rare gas systems

摘要: 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 pseudopotential model. The considered are those associated, the separated atom limit, with S–S S–D electric forbidden alkali atom. found to be relatively large (about 10−2–10−4) at small intermediate distances (R∼3–12 a.u.).
