Ra. Bonham et al., ON THE SLOPE OF THE GENERALIZED OSCILLATOR STRENGTH IN THE LIMIT OF ZERO MOMENTUM-TRANSFER, Journal of physics. B, Atomic molecular and optical physics, 26(19), 1993, pp. 3363-3378
The slope of the generalized oscillator strength in the limit as the m
omentum transfer, K, approaches zero contains information concerning t
he probability of certain nondipole transitions in atoms and molecules
. Sum rules and bounds are explored in an attempt to interpret experim
entally derived slopes in terms of the underlying physical processes.
We also discuss the slope and related quantities calculated for atomic
hydrogen,
