摘要

作为应用第一部分公式的例子，我们研究了一维介质中的散射，对于这种介质，辐射场的所有特征都可以用基本函数和（三维）各向同性单色散射来表示。我们研究了安巴苏姆函数的一些特性，并推导出光厚平面层中光子散射事件平均数量的渐近线。

Escape Probability and Average Numbers of Photon Scattering Events. II. Monochromatic Isotropic Scattering in a One-Dimensional Medium and Plane Media

As examples of applying the formulas from part I we examine scattering in a one-dimensional medium for which all the characteristics of the radiative field are expressed in terms of elementary functions and (three-dimensional) isotropic monochromatic scattering. Some properties of the Ambartsumyan function are studied and the asymptotes of the average numbers of photon scattering events in an optically thick plane layer are derived.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
