    Notes: Abstract The reliability of the relative sensitivity factor (RSF) approach for secondary ion mass spectrometry (SIMS) quantification of the leached layers on glass was investigated by measuring comparable samples of glass with SIMS and RBS (Rutherford backscattering spectrometry). The RSF factors were calculated using the nominal bulk compositions. Accurate results can be obtained only when the leached layer and the bulk glass have the same major elemental compositions (Si and O) and the matrix effect is inhibited. The concentrations of the different elements in the leached layer obtained from the comparable samples measured by SIMS and RBS are coincident within a factor of 2

    Notes: Summary It has been shown that the 15N nuclear reaction technique for hydrogen profiling can be used for the characterization of polymer films. With an optimized sample geometry, a depth resolution of 5 nm near the sample surface is achieved. A special γ-ray detector allows radiation damage in the sample to be minimized. Since the 15N technique discriminates between the hydrogen isotopes H and D, a suitable contrast between the different components of a polymer film is achieved by deuterating one component of the polymer. This has been utilized in the study of the surface-induced lamellar ordering within diblock copolymer films.
