Physics progress report, February 16--29, 1948

Description: Preliminary study of the characteristics of a now design of a tub type moderator for neutron counting reveals some definite advantages over the laboratory Hanson setup. Two determinations of the purity of postum were made with the vacuum balance apparatus. The first result was 94.81 percent postum and the second 100.5 percent. A redesigned effusion apparatus is described in detail, and results of nine exposures are presented. The data lie fairly close to a straight line on a log p vs 1/T plat, … more

Physics progress report, March 1--31, 1948

Description: The quarts gauge apparatus for measuring the vapor pressure of postum was completed. The first sample of postum oxidized in the course of preparation, while in a presumably sealed and evacuated quartz tube. an error of 0.4 per cent appears to be present in the vacuum weighing of postum. a diffusion pump is being installed to reduce the pressure, in the hope of minimizing the radiometer effect. Repetition of the effusion experiment with a rebuilt crucible yielded four points below those reported… more
