Abstract: "Geodimeter surveys were made on four traverses near the east scarp of Rainier Mesa between October 27, 1967 and April 26, 1968. These measurements were made in order to determine if an changes in distance between survey stations had resulted from downslope creep of the rocks behind the scarp, or if any displacements had resulted from nuclear explosions beneath the mesa and in adjacent areas. A persistent small but possibly significant, slopeward displacement was measured along one traverse and may represent detachment of a large block; monitoring for an additional period of time is recommended."

Observation of the long-term effects of weathering on 10 nuclear craters over periods as long as 12 years.

Under the stimulus of electronic materials development - particularly thin-film studies - and the need for space environmental simulation chambers, a very rapid increase in the availability of industrial-sized vacuum components and systems operable in the ultrahigh vacuum range has taken place in the last three years. It is the purpose of this paper to explore the design considerations of ultrahigh vacuum systems for metallurgical applications.

Nuclear excavation is the name given to the concept of using large scale nuclear explosion craters for useful projects, such as harbors, canals, and roadway cuts. It is one of the principal applications of the Plowshare Program for industrial, or peaceful, uses of nuclear explosives. Plowshare is sponsored by the U.S. Atomic Energy Commission and is under the technical direction of the Lawrence Radiation Laboratory at Livermore, California. The purpose of this paper is to describe cratering concepts and the present state of nuclear excavation technology. The general nature of the safety hazards associated with nuclear excavation are also discussed.

Report compiling the melting points of 70 metal oxides published prior to January 1963. Both the original melting point and the equivalent value based on the International Practical Temperature Scale of 1948 are presented. Included in the survey is information on pertinent experimental details such as the method of temperature measurement, purity, furnace type, and environmental conditions.

Technical report. From Abstract : "A system has been developed to program a digital computer in much the same manner as an analog computer is programmed. Properties of a general purpose analog computer and a digital differential analyzer are combined to yield a program which employs, as input, standard data cards prepared from a diagram analogous to an analog computer diagram. The capacity of the system is much greater than that of most analog computers, making it applicable to large simulation problems. No scaling is required. The system is compatible with the Fortran symbolic language and may be used as part of a larger digital computer program. It may be applied to the more general types of boundary value problems arising in process simulation in addition to the initial value problems ordinarily solved on analog computers. It is particularly well adapted to non-linear problems and to control problems involving large transport delays. The program operates in basic machine language and, when used by itself, requires no compilation time."

In-pile loop experiments L-2-15 and L-4-16 were two of a series designed to test the radiation corrosion of Zircaloy-2 and other possible reactor construction materials in UO2SO4 solutions under various conditions of radiation intensities, temperatures, solution compositions, and velocity flow past specimens.

Abstract. By means of the pulse radiolysis technique a short-lived transient species has been observed in irradiated de-aerated ethanol and methanol, exhibiting an optical absorption throughout the visible and near infra-red. This transient is suggested to be the solvated electron on the basis of the nature of the spectrum, the reactivity with hydrogen ion and with various organic electron acceptors, and the formation of mononegative ions of some of these acceptors. The absolute rate constants have been determined for the reactions of the solvated electron with hydrogen ion, oxygen and benzyl chloride in ethanol and methanol. The diphenylide ion was found to be short-lived in ethanol. The absolute rate constant for the first-order decay of the diphenylide ion has been determined.

Technical report. Form Abstract : "Perchlorate is extracted from aqueous solution by n-butyronitrile as ferrous 1,10-phenanthroline perchlorate. The amount of perchlorate is calculated from spectrophotometric measurement of the absorbance of the extract. Moderate to large amounts of chloride, sulfate, or nitrate cause little or no interference. Chlorate is slightly extracted but the interference can be corrected."

The alternating-gradient proton synchrotrons at CERN and Brookhaven are very similar in size, design and in their experimental use. For this reason, collaboration between the groups at CERN and Brookhaven has been close throughout the history of these two machines. For the most part this has taken the form of exchanges of visits of individual machine designers and of high-energy physicists. By 1962, however, it appeared that the reciprocal flow of information was not adequate and a more formal meeting was arranged. This meeting took place at Brookhaven during the week of September 10, 1962. CERN sent a representative group of machine physicists and high-energy physicists. The meeting was attended also by observers from several American high-energy installations. The discussion covered a wide range of topics, from operating characteristics of the machines themselves to future trends in design of experimental equipment. Plans for beam ejection were presented, techniques were described for better use of secondary beams from internal targets, progress was summarized on dc and rf particle separators. and future trends in neutrino experimentation were predicted.

Technical report. From Abstract : "Paramagnetic susceptibilities of samarium structure alloys in the systems La-Gd, Nd-Y, Nd-Tm, and Ce-Y were measured from 4.2 - 300°K to determine what effect the formation of this structure has on the magnetic properties of the alloys. Susceptibility maxima were observed in the Nd-Y and Nd-Tm alloys, at 34.5 and 28.5°K, respectively. Slope changes were observed in the curve of 1/x versus T for the La-Gd alloy at 155 and 130°K, and the susceptibility of this alloy remained temperature-independent from 130-7°K. A rather poorly defined region of constant susceptibility was also observed or the Ce-Y alloy, from 26-37°K. Above these transition temperatures, the alloys obeyed the Curie-Weiss law, the susceptibilities of the La-Gd and Ce-Y samples indicating the possibility of electron transfer occurring in these cases."
