Abstract

The experimental data available for (α,α) silicon elastic scattering cross section at angles and energies suitable for Ion Beam Analysis have been reviewed. The spectra of alphas elastically scattered from a thick uniform silicon target were measured with a small step over the entire energy range studied. The analysis of the data was made in the framework of the R-matrix theory, with potential scattering being taken into account using optical model. The obtained results provide the evaluated differential cross sections for silicon (α,α) elastic scattering in the energy range from Rutherford scattering up to 5.2 MeV.

    Figs. 4 and 5 show that the simulated cross sections are in good agreement with the SigmaCalc ones and thus our model correctly calculates cross section. However, the experimental cross sections often show deviations from the theoretical ones [34], [35], and deviations in RBS spectra are also expected. The benchmarking (made in SigmaCalc website) of the cross sections calculated by SigmaCalc against experimental spectra shows that in the higher energy regions significant deviations occur.

    The SigmaCalc [36] (v.2.0 [37]) code is publicly available, and can generate cross-section functions for any given scattering angle. Some of the important reactions have been published separately: these include the C [38,39], O [40], Mg [41], Al [42], and Si[43] reactions (for proton scattering, see Table 2); and the C [44], O [22], and Si[45] reactions (for alpha scattering). Where evaluated data are not available, measured data are taken from the collection in IBANDL [46,47].

    Thus, emerges a great need for the application of Ion Beam Analysis (IBA) techniques in order to acquire an accurate quantitative determination of silicon depth profile concentrations. Among all IBA techniques, Elastic Backscattering Spectroscopy (EBS) with protons [1] and alpha particles [2] is the most widely used for silicon depth profiling studies due to the existence of evaluated data in IBANDL (Ion Beam Analysis Nuclear Data Library, https://www-nds.iaea.org/exfor/ibandl.htm), via the online calculator SigmaCalc 2.0 (http://sigmacalc.iate.obninsk.ru/). However, an alternative, prominent IBA technique, especially in the case of thin or semi-thick films containing silicon in complicated matrices (e.g. silicides), is Nuclear Reaction Analysis (NRA), via the simultaneous implementation of the 28Si(d,p0,1)29Si reactions [3], for which recommended differential cross-section datasets at 150° already exist in IBANDL.

    The detailed consideration of the problems inherent in the benchmark experiment can be found elsewhere [7]. The importance of benchmarking has been recognized by the IBA community and nowadays the works in which this concept is employed are not rare in the literature (see e.g. [8–10]). Benchmarking is an important step in the evaluation methodology which provides an evaluator with a feedback for the next iteration of the cross-section evaluation.
