Abstract: | Oscillator strengths for 11S?n1P transitions for some members of the helium isoelectronic sequence have been calculated by utilizing the dipole length, velocity and acceleration forms of the transition matrix element with coupled H.F. wave functions. Good agreement has been obtained between the values of the oscillator strengths. The quantities and decrease slowly with nuclear charge Z, whereas first increase to a maximum value and then decreases slowly. |
