Cosmic Ray Produced Ar37 and Ar39 Activities in Recently Fallen Meteorites (open access)

Cosmic Ray Produced Ar37 and Ar39 Activities in Recently Fallen Meteorites

Several methods of determining meteorite ages depend ages upon nuclides formed by cosmic ray interactions. The tactic assumption is always made that the intensity of cosmic radiation does not vary in time or space. However it is known that the intensity of cosmic radiation at the earth varies with the solar activity. The spectrum of cosmic ray protons and alpha particles exhibit a marked drop at the low energy end (<1.5 GeV) and the intensity in the region appears to follow the 11 year cycle of solar activity. The low energy cosmic rays increase in intensity with a decrease in solar activity. These changes in cosmic ray intensities are generally attributed to a modulation of the galactic cosmic radiation by the magnetic fields associated with the outward streaming solar material, the solar wind. One would therefore expect that the cosmic ray intensity several astronomical units from the sun is greater than the intensity at the earth's orbit, particularly at the low energy end of the spectrums.

Dibutyl Carbitol Solvent Extraction of Polonium-210 from Nitric Acid Solutions of Irradiated Bismuth (open access)

Dibutyl Carbitol Solvent Extraction of Polonium-210 from Nitric Acid Solutions of Irradiated Bismuth

Abstract: "A continuous countercurrent solvent extraction process utilizing dibutyl carbitol as the extractant has been developed for separating 210Po from large amounts of associated bismuth. Both laboratory and pilot plant data demonstrate the process is a suitable headend step in recovery of kilogram quantities of 210Po. Typically, the extraction process recovers over 98% of the 210Po, essentially free from bismuth (Bi DF>1500), in a dilute HNO3 solution suitable as a starting material for final concentration and purification steps."

The Mg-MgCl2 System — A Chronopotentiometric Study (open access)

The Mg-MgCl2 System — A Chronopotentiometric Study

The mode of dissolution of magnesium in molten magnesium chloride contacted with Mg-Pb alloys was studied at 750°C using anodic chronopotentiometry. An inert tantalum anode was used to determine relative amounts of magnesium dissolved in its chloride as a function of magnesium activity in the alloy. According to the law of mass action a linear dependence of magnesium solubility on a Mg indicates Mg2Cl2 as the reaction product and a parabolic dependence indicates MgCl. It was found that the amount of magnesium dissolved in its chloride was directly proportional to the magnesium activity in the metal phase, i.e., a linear dependence, indicating Mg2Cl2 as the subhalide species. Due to the corrosive nature of the Mg-MgCl2 system a special apparatus was used so that only the inert metals tantalum and molybdenum came in contact with the melt. Purification procedures and conditions for proper equilibration and measurement were established and are reported. The basic equation of chronopotentiometry, [equation not transcribed], was found to hold and at given magnesium activities the product [unintelligible] did not vary with the current, indicating the validity of the analytical technique.

XLIBIT: ANL Cross-section Library Code

From Introduction: "With the acquisition by the Laboratory of a Control Data 3600 computer in the fall of 1963, a joint reprogramming project was undertaken by the Laboratory's Applied Mathematics Division and the Control Data Corporation to develop one - and two-dimensional diffusion-theory and Sn transport-theory programs for the CDC-3600. The XLIBIT code described in this report was developed as a part of this project. XLIBIT is a CDC-3600 program designed to: 1) Prepare a cross-section library tape. 2) Modify an existing cross-section library tape. 3) Duplicate an existing cross-section library tape. 4) Print all or a portion of the cross-section data on the library tape. Punch cross-section decks for all or a portion of the data on the library tape. The decks produced are identical to those used in pertaining the tape."
