Zur Kritik der musiksoziologischen Vernunfthich the theory is briefly outlined. If the thickness of the Au-contact layer is assumed to be known, the thicknesses of the Si-dead layer and of the Be-window have been determined from a least-squares fit to the experimental data, which were obtained at different X-ray energies. A mathematical simu

Sinndimensionen: Raum, Zeit, Selbst,model. It is shown that the SRIP-method applied to a non-linear model, converges steadily, if the model is properly chosen and thus, it can be used as a measure of the correctness of the model. This is accomplished by assuming the existence of at least one peak-described by a Gaussian formula-while

Preliminary results with the cathode lens in a classical SEM are presented and the new configurat

Historische Versuche der Physik For various combinations of metals and thin film materials, data concerning contrasts of the strips in Auger emission are presented. For different configurations the Auger image contrast varies in the magnitude and even contrast reversal is observed in the dependence on the primary energy. It even

https://doi.org/10.1007/978-3-663-10307-3limitations. In particular, cyclotron-based accelerator mass spectrometry (AMS) is discussed with an emphasis on the performances of superconducting minicyclotrons, designed for use as AMS instruments. If ionic and laser microexcitation are used in the ion source, the system would have a considerabl
