Abstract:

The model which is discussed in this report has been developed and programmed as an independent energy deposition and transport code, FSCATT. FSCATT represents a general and economical treatment of the effects of photoelectric absorption, fluorescence, and Compton scattering for problems in slab geometry. In the FSCATT program the intensity of the radiation field is computed in terms of finite angular and energy groups. The Klein-Nishina cross section is used and softening of the incident spectrum is permitted. Effects of polarization, inverse Compton scattering, and stimulated emission have been neglected. The results of calculations made using FSCATT and the Monte Carlo code PHOTRAN are compared in this report. Preliminary observations indicate that comparable results are obtained with substantially less computer time required using the FSCATT program. The scope of this report is limited to a discussion of the model and the presentation of some preliminary results. The FSCATT code will be documented in a subsequent report. Author
