The Biological Effects of heavy Cosmic Ray Particles (open access)

The Biological Effects of heavy Cosmic Ray Particles

Technical report investigates creating a microbeam of deuterons to simulate cosmic rays and the results of brain irradiation, irradiation of the eye, and irradiation of hair follicles of mice. The report's conclusion was that "astronauts exposed to heavy primary particles over a period of some weeks would be expected to develop gray hairs, but this is the only significant biological damage they would suffer."

A Bond-Cell Method for Complex Molecules and Metals (open access)

A Bond-Cell Method for Complex Molecules and Metals

This technical report introduces "some approximations into the basic quantum mechanical theory" so that the theory of the covalent bond and the molecular orbital method "can be combined into one which will yield quantitative rather than qualitative binding energies and cohesive energies and also distinct energy levels and band structure." This approach will provide a common method "suitable to both solid state physicists and physical chemists, for calculating the energy levels in metals and complex molecules." This report also contains figures detailing the findings. (Quotations taken from introduction)

Design Study for a 15-BeV Accelerator (open access)

Design Study for a 15-BeV Accelerator

This report is the culmination of a year of progress and planning in the high-energy particle field. During this year the Brookhaven Cosmotron has been successfully completed and brought into operation for research at 2.3 Bev. Preliminary experimental results with the copious output of π-mesons are in process of publication. Multiple production of mesons has been observed, a few V-particles detected, and the interactions of π-mesons in hydrogen have been studied. Yet it already appears that higher energies will be needed to produce and study the several new heavy particles detected in cosmic ray observations.

We have recently completed measurement of resonance escape probability in the BNL reactor and in several slightly-enriched uranium light water moderated lattices. In addition, WAPD has made available to us data from other slightly enriched uranium-water lattices, so that about 18 lattices in all have been done.

A New Chlorophyll from Green Bacteria (open access)

A New Chlorophyll from Green Bacteria

The green photosynthetic bacteria are characterized by the presence of either chlorobium chlorophyll (bacterioviridin)-65o or chlorobium chlorophyll-66o (numerical designation based on the position of the red-absorption peak in ether) z. Most strains of Chlorobium contain chlorophyll-66o which has its major red peak between 74 ° and 75 ° m/~ in FiFo. KATZ AND WASSINK z first reported an additional minor absorption peak at 81o mF for Chlorobium limicola in vivo and a corresponding minor peak at 780 m F in ethanol extracts. LARSEN (Figs. 6-11 in ref. 3) also observed this 8Io-mF absorption band in another Chlorobium strain and a corresponding peak at 77 ° m/~ in acetone extracts. In strain L of C. thiosulfatophilum the minor red peak appears at 800 mF, clearly resolved from the main peak of chlorophyll-65o at about 725 m/~ (see refs. I, 4). We have observed the minor red peak once again in Chloropseudomonas ethylicum, strain 2K (refs. 5, 6), as a shoulder at about 81o mF on the side of the 75o-mF peak of chlorophyll-66o (ref. 7). The evidence presented in this paper indicates that the absorption peak appearing between 800 and 81o m/, in vivo does not belong to chlorophyll-65 o (or …

On the Synergistic Effect in Solvent Extraction

The studies of Irving and Edgington, and Healy on the synergistic effects of tributyl phosphate (TBP) and tri-n-octylphosphine oxide (TOPO) on the solvent extraction of thorium and other metals by thenoyltrifluoroacetone (TTA) are discussed. It is shown that the synergistic effect is a result of addition reactions as well as replacement reactions and is not a function of the metal being extracted. A compilation of equilibrium constants describing the synergistic effect of TBP and TOPO on TTA extraction is given for the following metal ions: Th4+, UO2,2+, Am2+, Cm3+, Pm3+, Tm3+, and Ca2+.
