Secondary ion spectrometry has been used to follow the course of typical thermal emission mass spectrometric analyses of U samples loaded on single anion resin beads. It was found that U stayed almost entirely in the carbon matrix remaining after the

Secondary ion mass spectrometry (SIMS) has been used for the rapid, accurate analysis of B and Li in various nuclear materials. The problem of sample charging observed in the analysis of insulator materials has been overcome by distributing the sampl

In-situ formed oxide coatings have been proposed as hydrogen permeation barriers for candidate materials in heat exchangers and for hydrogen containment. In this regard oxides formed by oxidation of Incoloy 800 in 243 and 532 torr (1 torr = 133.3 Pa)

The method uses basic anion resin to adsorb plutonium and uranium from 7–8 M HNO3 solutions containing dissolved spent reactor fuels. After equilibrating the resin with the solution, a single bead is used to determine the isotopic composition of pl

The absorption of CO2 laser radiation in p‐type GaAs is dominated by direct free‐hole transitions between states in the heavy‐ and light‐hole bands. For laser intensities on the order of 10 MW/cm2, we report that the absorption associated wit

Ion implantation standards were used to calibrate a spark source mass spectrometer (SSMS) near surface region analytical method. Standards were prepared by ion implanting 11B+ at 100 keV into Zircaloy-2 at doses in the 3 × 1015 to 3 × 1016 11B atom

An innovative ultrasensitive technique was used for lead isotopic analysis of individual zircons extracted from granite core samples at depths of 960, 2170, 2900, 3930, and 4310 meters. The results show that lead, a relatively mobile element compared
