A Kinetic Study of CO2 Desorption From Thoria

Description: "Desorption rate curves were obtained for carbon dioxide absorbed on thoria at temperatures of 550C, 450C, 350C, 250C, 150C, and 50C. The gas were found to desorb according to a logarithmic law following initial rapid desorption. The logarithmic law may be shown to be operative if the activation energy for desorption varies linearly with surface converge. A large apparent negative entropy of activation for desorption supports the fact that the adsorbed CO2 is in a mobile state."

A Monte Carlo Study of Neutron Thermalization

Description: "The slowing down of neutrons from fission to absorption energies in a homogeneous medium has been treated by a Monte Carlo method. thermalization by elastic collisions in both light and heavy water was computed on an IBM 650. One-sixth the mean-square distance travelled by the neutrons was interpreted as the migration area. This quantity was analyzed to give the age, t, both above and below the indium resonance, and the thermal diffusion constant. D, as functions of the moderator temperature, … more

Properties of Nuclear Matter

Description: "An account is given of recent theories by Brueckner, Eden, Swiatecki, Bethe, and co-workers about the properties of nuclear matter, which is identical in content, but different in its method of presentation. This presentation tries to clarify the reasons for the applicability of the independent-particle model and to determine what particular features of the nuclear forces are responsible for the validity of this model."

Technical Progress Report

Description: "Discussions on the high-speed computer program include test control design, core storage unit, magnetic drums and tapes, paper tapes, slow circuits, exponent and main arithmetic units, flow charts for arithmetic control, and speed independent designs. Work done in the circuit research program includes flow-gating systems tests and two-wire low swing circuits. Mathematical methods are described for experiments with a floating-point differential equation solver. Switching circuit theory developm… more
