ENERGY RECEPTION AND TRANSFER IN PHOTOSYNTHESIS

Description: The basic information about the path of carbon in photosynthesis is reviewed together with the methods that were used to discover it. This has led to the knowledge of what is required of the photochemical reaction in the form of chemical species. Attention is then directed to the structure of the photochemical apparatus itself insofar as it is viewable by electron microscopy, and some principoles of ordered structure are devised for the types of molecules to be found in the chloroplasts. From t… more

THE PHOTOVOLTAIC EFFECT AND PHOTOCONDUCTIVITY IN LAMINATED ORGANICSYSTEMS

Description: As a result of a wide variety of studies on photosynthesis in living plants and plant fragments, together with the development of photosensitive, photovoltaic junctions in inorganic crystals and the discovery and exploration of semiconduction in organic molecular substances, a suggestion has been made that the primary quantum conversion process in photosynthetic tissues involves the creation and separation of charge to opposite sides of an asymmetrically-constructed lamina, followed by the trap… more

17-keV x-ray output of plutonium

Description: In the production of plutonium in a reactor, plutonium-238, 240, and 241 are formed as well as Pu{sup 239}. It is well known that the specific alpha activity of the plutonium varies as the percentages of these isotopes are changed. Kinderman, et al have worked out the relationship between isotopic content and MWD/ton exposure. Their findings are reported in this document.

IDP physics primer

Description: In this document it is proposed to describe the plant site and to outline the nature of the pile in order to show the specific design and layout requirements for the production of plutonium by nuclear synthesis. The selection of the plant site involved a number of special considerations. An essential requirement was a large dependable supply of relatively pure water that remains at a fairly low temperature throughout the year. A large source of power was required to circulate the tremendous qua… more

A proposal for equitable IPD electrical power cost distribution between areas

Description: Assistance has been requested by Financial Operation to determine the percent of firm and interruptible power used in each area for cost distribution purposes. Also, Power Operations have suggested that the power cost distribution be reviewed. In consideration of these requests, and with the use of improved demand instrumentation within the 151-B, D, and F substations, a proposal for equitable IPD electrical power cost distribution between areas is presented for acceptance or comment by Area Ma… more

Reactor Components Study

Description: Reactor operating conditions are formally established to conserve pile life. A major part of the 2000 Research and Development effort is oriented to develop fundamental information required to properly establish these limiting operating conditions. This report reviews the current condition of reactor components believed important to continued productive life of the reactors and discusses the current status of technologies important in estimating the future productive life of the reactor complex… more

Delayed Light Emission in Green Plant Meterials:Temperature-Dependence and Quantum Yield

Description: The discovery of the delayed light emission of plant materials by Strahler and Arnold in 1951 has stimulated a good deal of interest in this rather remarkable property. The emitted light has been shown to be due to an electronic transition between the first excited singlet state of chlorophyll and the ground state. At room temperature, a luminescence is observable from about 0.01 seconds to several minutes after excitation. Thus, the electronic transition cannot be rate-determining and the proc… more

Temperature and Phase Effects on the Photolysis of Ethyl Iodide

Description: The elementary sieps in the photolysis of liquid ethyl iodide by light of wavelength 2537 A by determining initial rates of iodine production in the presence.of added iodine and hydrogen iodide were analyzed at 25 and --70 d C to get information on the activation energies of competing elementary reaciions. Investigations were also made of the effects of additives on the photolysis of glassy ethyl iodide at --180 d C, and evidence for the formation of trapped radicals during photolysis and radio… more

ELECTRICAL AND OPTICAL INVESTIGATION OF CHARGE-CARRIER TRAPPING IN RUTILE SINGLE CRYSTALS. Technical Report No. 27

Description: Low-frequency abeorption centers, observed by electrical measurements in single crystals of rutile, can be produced by thermal quenching or optical irradiation in the edge of the eigen absorption region (600 A). They are observed when electric fields are applied parallel to the optic axis (crystallographic c axis) and are not visible with the field perpendicular to this axis. The temperature dependence of the principal dispersion indicates an activation energy of 0.18 ev. The centers can be exp… more

GAMMA RAYS ASSOCIATED WITH FISSION

Description: Measurements of the energy spectra and time distribution of the fission-associated gamma rays are described. New data for thermal neutron-induced fission in U/sup 235/ is presented covering the energy range between 0.3 and 8.0 Mev. Gamma-ray energy analysis was carried out with a multiple-crystal scintillation spectrometer employing either Compton scattering of pair production to give unique pulse-height response. The importance of unique spectrometer response is explained. The gamma-ray spectr… more
