Universal formula to extrapolate the generalized oscillator strength through the unphysical region to [ital K][sup 2]=0
Abstract
Rigorous bounds are derived for the momentumtransfer squared, [ital K][sup 2], and used to construct a universal formula to extrapolate the generalized oscillator strength through the unphysical region to the optical oscillator strength. Results of the universal function are compared with those obtained from experimental smallangle differential cross sections to determine the range of its applicability.
