EFFECT OF SCATTERING ON THE CONTOUR OF THE RADIATION LINE OF A PLANE LAYER OF A SELECTIVE MEDIUM M. L. German , D. Lempert , V. P. Nekrasov , E. F. Nogotov , and S. Rozin UDC 536.34:535.36 An analytical expression for determination of the correction factor which allows for effect of scattering on the contour of the radiation line of a plane layer of a selective medium is presented. Errors of calculation of the intensity of radiation which arise when this effect is neglected are analyzed. The study is based on a numerical solution of the integro-differential transfer equation.
