The common methods of neutron detection are reviewed with special attention paid to the application of cryogenics and semiconductors to the problem. The authors' work with LiF- and boron-based cryogenic instruments is described as well as the use of
Cryogenic calorimeters are used for x-ray detection because of their exquisite energy resolution and have found application in x-ray astronomy, and the search for dark matter. These devices operate by detecting the heat pulse produced by ionization i

Insights into the transport and deposition of oxygen in silicon oxidation at 700/sup 0/C were obtained by isotope labeling and use of the ion microprobe mass analyzer for profiling. The results are consistent with interstitial diffusion of O/sub 2/ a

The discovery of embryonic halos around uranium-rich sites that exhibit very high (238)U/(206)Pb ratios suggests that uranium introduction may have occurred far more recently than previously supposed. The discovery of (210)Po halos derived from urani

POLONIUM radiohaloes occur widely and not infrequently (total about 1015–1020) in Precambrian rocks but their existence has so far defied satisfactory explanation based on accepted nucleocosmogeochemical theories1. Do Po haloes imply that unknown p

GIANT haloes1–3 attracted little attention until it seemed that those from Madagascar2 might be associated with superheavy elements4. Even though this association was not confirmed5, this renewed interest has generated several additional suggestion

A modified rotating cryostat and its use for in situ infrared studies are described. An improvement in sensitivity over present low temperature infrared cells and much shorter deposition times have been obtained.

The ability of the ion microprobe or SIMS instrument to distinguish between isotopes and to analyze thin layers sequentially by sputtering provides unique methods well suited for studying oxidation and corrosion mechanisms. Although many SIMS studies

Corrosion of metals is an extremely important field with great economic and engineering implications. To effectively combat corrosion one must understand the processes occurring. This paper shows the utility of SIMS data for elucidating the process
