THE TRANSMISSION MATRIX METHOD FOR PENETRATION PROBLEMS. Period covered: December 1958 through November 1959
BS>A practical machine method for computing transmission and reflection of radiation by laminated slab shields is described, making use of transmission and reflection matrice. these are combined in a way which produces a formal solution of the Boltzmann equation in slab geometry. This result is appiled by using representations in terms of energy groups and angular expansions. Two cedes for the IBM-704 which together carry out the computation of the transmission and reflection matrices are described and operating instructions are given. Numerical results for gamma rays are presented. The advantages of the transmission matrix method as compared to other methods are discussed. Appendices are included showing how in the P/sub 1/ approximation the method gives diffusion theory in a particularly simple way and how it can be appiled to other geometries. (auth)
