On definition and measurement of extinction cross section

Mishchenko, M., M. J. Berg, C. M. Sorensen, and C. V. M. van der Mee (2009), On definition and measurement of extinction cross section, J. Quant. Spectrosc. Radiat. Transfer, 110, 323-327, doi:10.1016/j.jqsrt.2008.11.010.

Following the recent analyses of extinction by Berg et al. [J Opt Soc Am A 2008;25:1504–1513; J Opt Soc. Am A 2008;25:1514–1520], we show that although it is possible to define and measure the extinction cross section for a single particle using a detector of light facing the incident beam, this requires certain theoretical assumptions and experimental precautions.
