Nonadiabatic effects in single-particle orbits

Description: From introduction: "The containment of a charged particle in a mirror field has been studied analytically and numerically. Formulas are presented which give the change in the magnetic moment as it passes from one end of the machine to the other."

The nuclear spins, hyperfine structure separations, and magnetic moments of Cs¹²⁷, Cs¹²⁹, Cs¹³⁰, and Cs¹³²

Description: From abstract: "The nuclear spins, hyperfine structure separations, and magnetic moments of four cesium isotopes have been measured, using an atomic beam magnetic resonance apparatus designed to utilize the low background flop-in method."

Aqueous Corrosion of Uranium Fuel-Element Cores Containing 0 to 20 w/o Zirconium

Description: Abstract: A description is given of the design and operation of a windowed autoclave system employed in the study of corrosion by pressurized hot water. The device has been used to obtain time-lapse motion pictures of the swelling and rupture of deliberately defected zirconium-clad uranium specimens. A method is described by which corrosion rates were calculated from pressure and temperature measurements. A typical set of pictures taken during a test is presented, and corrosion rates are reported for uranium-0, 5, 10, 15, and 20 w/o zirconium alloys subjected subjected to 600 F water.

Analysis of uranium hexafluoride-hydrogen fluoride solutions by freezing point determination : errors caused by liquid -vapor equilibrium

Description: A report detailing the analysis of uranium hexafluoride-hydrogen fluoride solutions by their freezing point determination. This analysis was conducted by measuring vapor pressures at the freezing temperatures of different compositions of uranium hexafluoride-hydrogren fluoride solutions.

Analytical methods and results

Description: Report detailing the analytical methods and results of a study designed to measure the total alpha particle activity of samples. The method being used was previously in use at Columbia University. The report recognizes potential for grave errors, but makes no effort to minimize the effect of the roughness of the sample.

Analytical procedure for determination of tuballoy in solid salvage residues

Description: From abstract: Test results indicate that the hydrofluorination method for the analysis of tuballoy in solid salvage residues yields sufficient results with a high degree of accuracy; while a modification of the procedure gives good results in approximately half the time.

Temperature distribution in spherical pellets

Description: From abstract: "A study is presented of the surface temperature distribution of spherical pellets in a fixed-bed, pellet-type reactor. The temperature near a point of contact is determined experimentally by means of an electrolytic tank analogue. An analytical approach involving the use of the IBM (CPC) calculator is described. Suggestions for further study are included."
