oscillator strength

[′äs·ə‚lād·ər ‚streŋkth]
(atomic physics)
A quantum-mechanical analog of the number of dispersion electrons having a given natural frequency in an atom, used in an equation for the absorption coefficient of a spectral line; it need not be a whole number. Also known as f value; Ladenburg f value.
