The dependence of the neutrino total cross section sigma /sub nu / on neutrino energy was measured up to 160 GeV. The data are consistent with a linear dependence with slope (0.58 plus or minus 0.25) x 10/sup -38/ cm/suup 2/ GeV. The ratio of the antineutrino to the neutrino total cross section sigma / sub nu / sigma /su b nu / was found to be approximately constant up to 70 GeV at a value which is consistent with the numerical value of 1/3 expected for the scattering of neutrinos and antineutrinos by relativistic pointlike spin 1/2 fermions.

The behavior of inert gases, particularly helium, in metals was studied in aluminum, copper, niobium and stainless steel. Emphasis was upon characterizing the state of helium in the metals and upon following the kinetics of precipitation and coalescence. Experimental techniques that are, in most cases, new to studies of inert gases in metals were employed. These include low- temperature specific heat, precision lattice parameter measurement, internal friction, computer simulation, and residual resistivit gamma , in addition to confirmatory electron microscopy. The single most important finding is that bubble coalescence takes place at rates which are much slower than was previously supposed and that the slow coalescence fits a model in which the bubble mobility required for coalescence is rate-limited by nucleation of facets on the bubble surface. The further understanding and subsequent potential ability to control rates of bubble and/or void coalescence will be important to the design of nuclear fuel and cladding materials. (auth)

ABS>The U. S. Geological Survey has identified 1.5 million acres (2800 square miles) of western lands as having a significant potential for geothermal development.'' The LASL for the past 2 years has been actively investigating the potential for and preblems associated with extracting geothermal energy from the much more numerous regions of the western United States containing hot, but essentially dry, rock at moderate depths. A recent survey reveals that about 7% of the 13-state area comprising the Western Heat Flow Province---about 95,000 square miles--is underlain, at a depth of 5 km (16,400 ft), by hot rock at temperature levels above 290 deg C (>550 deg F). In the Los Alamos concept a man- made geothermal reservoir would be formed by first drilling into suitably hot rock, and then creating a very large surface area for heat transfer using conventional hydraulic fracturing techniques developed by the oil industry. After forming a circulation loop by drilling a second hole into the top of the fractured region, the heat contained would be convected to the surface by the buoyant circulation of water, without the need for pumping. The water in the Earth loop would be maintained as a liquid throughout by pressurization …

The Prandtl--Reuss equations used in the HEMP elastic-plastic computer program are satisfied exactly for elastic, perfectly plastic materials, and are less exact for materials that strain harden. A new method is described for incorporating strain hardening into the flow law that is exact for linear strain hardening and very nearly exact for nonlinear strain hardenlng. A tensile test of a strain-hardening material is simulated using the present method and the previous method. The original approximate method has an accumulated error of less than 2% when compared with the present method. The present method agrees with exact calculations to within 0.05%. (auth)
