“…For example, the 12 C(p,γ) 13 N reaction is critical to understanding stellar hydrogen burning in massive stars, initiating the CNO cycle. Fig.2 shows the "S-factor" for this reaction V , near the resonance at 461 keV (centre of mass frame), which is also observable in the elastic scattering 12 C(p,p) 12 C reaction channel at 440 keV (laboratory frame: see Fig.3 [40]). This S-factor is calculated using the AZURE code of Azuma et al [41].…”

Analysis using MeV ion beams is a thin film characterisation technique invented some 50 years ago which has recently had the benefit of a number of important advances. This review will cover damage profiling in crystals including studies of defects in semiconductors, surface studies, and depth profiling with sputtering. But it will concentrate on thin film depth profiling using Rutherford backscattering, particle induced X-ray emission and related techniques in the deliberately synergistic way that has only recently become possible. In this review of these new developments, we will show how this integrated approach, which we might call “total IBA”, has given the technique great analytical power

Characterisation of ancient Roman wall‐painting fragments using non‐destructive IBA and MA‐XRF techniques

Scientific investigation is very important in studies addressing issues of archaeological and historical objects. Ion beam analysis (IBA) and macro X‐ray fluorescence (MA‐XRF) spectroscopy are remarkable tools to obtain information about elemental composition and imaging of historical artefacts with a non‐invasive character. These investigation techniques were employed in the framework of a project aimed at supporting the characterization of materials and techniques related with the Roman wall painting. The archaeological excavations at Villa della Piscina in Rome have revealed a luxury building with a large pool (about 50 m long) and thermal baths and numerous fragments of plaster, coming from intentional demolitions referable to two distinct architectural contexts of the Villa during the imperial age, have been found. This work deals with studying the interesting wall pictorial apparatus of great cultural value of the heritage inherited from the Roman age in the area of the ancient city of Rome. The colour palette of the pigments investigated, in particular, by MA‐XRF and particle‐induced X‐ray emission (PIXE) and has revealed Fe, Cu, Pb, Si and Hg as main elements. Traces of other constituents uncover the choice of the different colours chosen by the artists who had embellished the rooms of the Villa.

“…In the past, benchmarking results have usually been reported, related to the validity of specific experimentally determined differential cross-section datasets [e.g. [3][4][5]. However, such measurements have never been performed in a systematic and consistent way, taking into account all the fine steps and details of the benchmarking process.…”

The benchmarking procedure in IBA regards the validation of charged-particle differential cross- section data via the acquisition of EBS spectra from uniform thick target of known composition followed by their detailed simulation. In the present work such benchmarking measurements have been performed for the elastic scattering of protons on 23Na, 31P and natS in the energy range of 1– 3.5 MeV in steps of 250 keV at three backward angles, at 120.6°, 148.8° and 173.5° in order to validate the corresponding existing evaluated cross-section datasets from SigmaCalc and to facilitate their extension at higher energies. The measurements were performed using the 2 MV Tandetron Accelerator of the Ion Beam Center of the University of Surrey. The EBS spectra acquired were compared with simulated ones using the DataFurnace code, along with an a posteriori treatment of the surface roughness. All the experimental parameters were thoroughly investigated and the results obtained and the discrepancies found are discussed and analyzed. Moreover, the benchmarking procedure in complicated cases, such as the natB(p,p) studied at NCSR “Demokritos”, where background contributions exist, is also discussed.
