"An experimental study has been made regarding the passage of a beam of 100-kV ions (H⁺ and H₂⁺) across a magnetic field by means of a crossed electric field." This experiment was designed to answer the following questions: "(1) Is there a limit to the current that will traverse a magnetic field by the action of a crossed electric field? If so, what is the limit? (2) Do difficulties arise in maintaining the electric field? (3) For the source employed, what is the angular divergence and current density of the beam?"

This is the monthly report for the Hanford Laboratories Operation, April, 1959. Metallurgy, reactor fuels, chemistry, dosimetry, separation process, reactor technology, financial activities, visits, biology operation, physics and instrumentation research, and employee relations are discussed.

The hot press process has been altered so as to eliminate the slight wrinkling near the ID base. This was done by incorporating a three minute time delay in the pressing cycle. The pressing time was decreased to five minutes to restrict formation of the brittle intermetallic compound, Ni{sub 2}Al{sub 3}.

Laboratory experience on the precipitation of Pu(IV) oxalate is summarized. Filterable Pu(IV) oxalate with a cake density of 0.6 to 0.7 g Pu/cm/sup 3/ cake was precipitated from Redox PR solutions containing 10 to 200 g/l Pu and 2 to 6 M HNO/sub 3/. Filtration ease increased with strike temperature from 35 to 60/sup 0/C. Optimum conditions for pre-reduction of Pu(VI) to (IV), precipitation, digestion, filtration and washing were determined for 60 g/l Pu. Separation factors of 80, 40, 20, and 12 for Al, Cr, Fe, and U and decontamination factors of 1.2, 12, and 3 for Am, Ru, and Zr--Nb were obtained.

The objective of this study is to provide a simple method for calculating exposures for the various laboratory procedures which involve penetrating radiations. With this method it will be possible to evaluate and record on a day to day basis the total exposure received during laboratory work. It will also provide reliable information for exposure investigations.

Introduction: During the year 1952-1953, research on the Boulder batholith program was largely devoted to basic mineralogy studies of the "siliceous reef" and, to the extent possible at that time, the "base metal" deposits.

The thermal conductivity of the gradient medium plays a very important part in the development of a calorimeter. It is a large factor in determining the sensitivity. The thermal conductivity apparatus was built primarily to find out why the measured sensitivities of the microcalorimeters were so much smaller than the calculated values. This question haa been resolved. The apparatus is now being used to study the thermal conductivity of Santocel, a granular insulating material produced by Monsanto Chemical Company. The Interesting fact is that though this material is in the solid phase it has a lower thermal conductivity than air. In a previous quarterly report approximate evidence was submitted to show that Santocel A has a lower conductivity than air at room temperatures. This result was worth verification, since this material would then prove useful in the construction of microcalorimeters. A verification is submitted in this report.

The idea of ''antiparticles'', as is well known, originated with Dirac, who in establishing the relativistic equations for the electron noted that besides the solutions corresponding to ordinary electrons there were also ''unwanted solutions'' corresponding to particles of electronic mass but of charge +e instead of the electronic charge - e. The discovery of the positron by CD Anderson offered a brilliant experimental confirmation of Dirac's prediction and gave the first example of an ''antiparticle.''

The essential structural element which differentiates metal chelate compounds from metal coordination compounds, or metal complexes in general, is the existence of some linkage between two or more of the donor atoms in the first coordination sphere of the metal. It is the purpose of the present discussion to examine the influences that this structural factor may have upon the physical and chemical properties of chelate compounds. Examples of well known, simple coordination compounds involving a variety of donor atoms (Oxygen, nitrogen), as well as a variety of electrostatic situations are shown in the following formula. Below each one are listed a few corresponding chelate structures.

In anticipation of the availability of the phase-shifts and mixing parameters, which are being calculated by Bransden, Smith, and Tate for the elastic scattering of nucleons by deuterons (with tensor forces), the von Neuman density matrix and Racah algebra were used to derive expressions for the average value of the spin operator in the emerging beam of nucleons after single and double scattering from unpolarized deuterons. The values of the geometrical factors which appear in these expressions were calculated on an IBM-650 digital computing machine and are given in the form of tables. The range of the angular momentum quantum numbers was chosen to cover nucleon-nucleon and nucleon-deuteron prolems up to J, the total angular momentum, equal to five. (auth)
