14-Year 113Cd

Description: The half lives of Cd/sup 113m/ and Cd/sup 115m/ have been redetermined to be 14 sintering time 2 years and 44.2 sintering time 0.5 days, respectively. The ratio of Cd/sup 113m/Cd/sup 115m/ yields from thermal-neutron fission of U/sup 235/ is 0.27 sintering time 0.03, and the ratio of (n, ) formation cross sections is 0.31 sintering time 0.03. Combination of these ratios with literature values for the Cd/sup 115m/ fission yield and (n, ) formation cross section gives (1.9 sintering time 0.2) x 1… more

A 704 Program for Computing Thermal Neutron Spectra in Infinite Homogenous Media

Description: A flexible program has been prepared for solution of the neutron balance equation in an infinite homogeneous medium. This program is specifically designed for studying the effects of varying the energy transfer kernel on the resultant neutron spectrum. A rapidly converging iterative procedure is employed. The equation to be solved and the specific input information required by the program in order to compute spectra are explicitly stated. No discussion of the physics of the problem is given.
