Determination of L III subshell photoelectric parameters of iridium.

The L III subshell photoelectric cross section, jump ratio, jump factor, and Davisson-Kirchner ratio of iridium have been determined by mass attenuation coefficients. The measurements have been performed using the X-ray attenuation method in narrow beam geometry. The obtained results have been compared with the tabulated values of XCOM (Berger et al. XCOM: Photon cross section database (version 1.3). NIST. Available at . 2005) and FFAST (Chantler et al. X-ray form factor, attenuation and scattering tables (version 2.1). NIST. Available at . 2005). [ABSTRACT FROM AUTHOR]
