On the qualitative features of the generalised oscillator strengths of ns-electron ionisation transitions

The generalised oscillator strengths f if l (Q) for atomic ns-electron transitions (n=1-4) to continuum states with energy E=0 and orbital momentum l from 0 to 6 have been calculated in the Born approximation with Coulomb wavefunctions. The importance of the functions f if l (Q) in forming the characteristic dependence of the total generalised oscillator strengths f if l (Q), for transitions of those electrons to all free states with E=0, the momentum transfer h(cross)Q has been considered. A qualitative relationship has been established between the structure (minima and maxima) found in f l (Q), f if (Q) and structural features of the radial wavefunctions of the initial and final states.
