Multigroup formalism for evaluation of continuous slowing down theory parameters

Description: Continuous slowing down theory calculations have been found to yield significant discrepancies in the presence of strong absorption. An algorithm has been formulated for evaluating continuous slowing down theory parameters which should be applicable for cases with strong absorption. Excellent agreement with more precise calculations is obtained when the new parameters are used.

Thermal properties. Period covered: October--December 1975

Description: The thermal decomposition investigation of PETN using an LX-13 type PETN was begun this quarter. Samples are being conditioned at 373, 353 and 333/sup 0/K and others will be conditioned at 393 and 383/sup 0/K. Data from five samples are reported. A series of chemical reactivity tests was made using PETN to determine if decomposition rates could be calculated from the results. The data fit a semilogarithmic plot of the gas evolved as a function of time reasonably well. The last of a series of HN… more
