Abstract

We obtain a simple integral formula for the radius distribution function or polydispersion n(r) in terms of the multispectral extinction τ(k), where k is the wavenumber. This formula is valid when the extinction coefficient is given by the anomalous diffraction approximation and n(r) vanishes faster than r as r → 0 for some positive .
