The X-Ray Spectra of Polonium Atomic Number 84
From abstract: "Two samples, each containing an estimated 10 curies (2 mg) of polonium-210, were purified by vacuum distillation and evaporated onto oblique sections of X-ray targets made of copper. Four lines of the K series and ten lines of the L series of the X-ray spectrum of polonium were recorded with a one-meter transmission crystal spectrograph and a 25-centimeter Bragg spectrograph, respectively. Measured wavelengths agree approximately with values predicted by extrapolation of Moseley's law and with those claimed by Hulubei. Decay of polonium-210 (half life = 138 days) and growth of lead-206 (stable) were observed over a period of 180 days."

Equations for Bilateral Heat Transfer to Fluids Flowing in Concentric Annuli
Abstract: "Theoretical equations have been derived for calculating heat transfer coefficients for fluids flowing through concentric annuli for the following two cases: (A) constant and equal heat fluxes from both walls, and (B) constant, but unequal, heat fluxes from the walls, with equal wall temperatures at a given axial position along annular channel. In the derivations, the conditions of fully-established flow, and independence of physical properties with temperature variation across the flow channel, were assumed. The only geometrical parameter in this general case is the radius ratio r2/r1, and in the study it was varied from 1.0 to 10.0."

Summary of Operating Experience with Decelerating Ion Receivers
From abstract: "The following report presents a summary of operating experience with decelerating receivers for ion beam reception. Sample calculations for design of such a receiver for the isotopes of lithium are presented. Estimates of maximum production and requirements to attain such production are given. The maximum ion beam envisioned is 17 amperes obtained from extrapolation of experimental results."

The Solvent Extraction of Thorium by Thenoyltrifluoroacetone and the Influence of Aqueous Complexation by the Chelating Agent
Technical report investigating the solvent extraction of thorium. The solvent extraction of thorium by the chelating agent, thenoyltrifluoroacetone (TTA), has proved to be a very effective tool for studying the complex ion chemistry of thorium. This study led to the establishment of the existence of aqueous complexation by the chelating agent.
