Trace elementary concentration in enamel after dental bleaching using HI-ERDA

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2006
Abstract Changes of elementary concentrations in dental enamel after a bleaching treatment with different products, is presented, with special focus on the oxygen contribution. Concentrations for Ca, P, O and C and some other trace elements were obtained for enamel of bovine incisor teeth by HI-ERDA measurements using a 35 Cl incident beam and an ...

Quantitative analysis of thin film compositions using EFTEM combined with RBS and ERDA

Microelectronic Engineering, 2007
Analytical electron microscopy today is an emerging technique allowing for the composition analysis of solids with high spatial resolution down to 1nm or less. In particular energy filtered transmission electron microscopy (EFTEM) is becoming a technique which is frequently applied to study nanometric semiconductor device features. Among the advantages

Quantitative trace hydrogen distributions in natural diamond using 3D-micro-ERDA microscopy

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1998
Abstract A 3-D quantitative microscopy for minor distributions of surface and near-surface bulk hydrogen in solid samples has been developed. The technique employs a 15 MeV Si 7+ microbeam and a two-dimensional position sensitive detector (2D PSD) with event reconstruction in an Elastic Recoil Detection Analysis (ERDA) geometry.

Quantitative microstructure characteristics of landslide soil affected by Three Gorges Reservoir with using ERDAS

The 2nd International Conference on Information Science and Engineering, 2010
The study on soil microstructure has transferred from qualitative description to quantitative analysis as the improvement of image processing technology. However, it is difficult that how to apply the quantitative technology to solve practical problems. We used ERDAS to quantify microstructure images of landslide soil in the Three Gorges Reservoir area,

Complementary use of ERDA and RBS/C for the determination of implanted atom and damage distributions in spinel

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2005
Abstract Crystalline oxide ceramics (particularly, zirconia and spinel) are promising matrices for nuclear waste immobilization and/or transmutation. The behavior of implanted ions and of radiation damage is a very important issue in the qualification of nuclear matrices. Ion beams provide very efficient tools for such an evaluation.

Characterization of carbon implanted fused silica samples using RBS and ERDA

2006
Fused quartz implanted with C ions with different energies and implantation doses were investigated using non-Rutherford Backscattering Spectroscopy and Elastic Recoil Detection Analysis. Samples were analized under same conditions before and after annealing in forming gas to study mobility of carbon and hydrogen atoms in the substrate.

Determination of hydrogen content in geological samples using elastic recoil detection analysis (ERDA)

Geochimica et Cosmochimica Acta, 2009
Abstract The present study illustrates the interest of using the elastic recoil detection analysis (ERDA) method to characterize any geological sample matrix with respect to hydrogen. ERDA is combined with Rutherford back scattering (RBS) and particle induced X-ray emission (PIXE), allowing the simultaneous characterization of the matrix with respect

High energy ERDA with very heavy ions using mass and energy dispersive spectrometry

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1992
The capabilities of the elastic recoil detection analysis (ERDA) method for depth profiling are investigated using high energy very heavy ion beams with energies close to the Coulomb barrier from the VICKSI accelerator and mass and energy dispersive recoil spectrometry by means of a time-of-flight energy detector telescope.

Simultaneous multielement ERDA using a simple detector system and extremely heavy ion beams

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996
Abstract The use of very heavy ion beams such as Au or Bi in elastic recoil detection analysis (ERDA) is increasing rapidly. However, one of the experimental problems is the simultaneous detection of the full range of recoil atoms ejected by such extremely heavy ion beams, since all low-mass surface recoils have almost identical velocity and also ...

Analysis of hydrogen in corrosion product films on molybdenum and niobium using ERDA technique

International Journal of Hydrogen Energy, 1999
Elastic Recoil Detection Analysis (ERDA) technique with 1H(α,α)1H forward scattering was used at 3.0 MeV to analyze hydrogen in corrosion product films formed on molybdenum and niobium surfaces at selected potentials of the anodic and cathodic potentiodynamic scan.
