“…The accuracy of the incident beam energy is about ±10 keV. This was determined by using the 27 Al(p,c) 28 Si reaction at 992 keV, by matching peak positions from an Al EBS spectrum modeled using the SigmaCalc cross-section [18] at 1598 keV and by matching peak positions from an Al EBS spectrum modeled using the cross-section from [19] at 2890 keV. The incident beam energy spread is below 1 keV.…”

a b s t r a c tThe cross-sections for the 9 Be(p,d 0 ) 8 Be nuclear reaction and for 9 Be(p,p 0 ) 9 Be backscattering were measured at a laboratory scattering angle of 165°in the energy range from 400 to 4150 keV, the cross-section for the 9 Be(p,a 0 ) 6 Li nuclear reaction was determined in the energy range from 400 to 1300 keV. The cross-sections were determined using thin films. The absolute accuracies are about 4.4-8.6% for the backscattering, 4.6-24% for the 9 Be(p,d 0 ) 8 Be nuclear reaction, and 4.5-5% for the 9 Be(p,a 0 ) 6 Li nuclear reaction cross-section. The derived cross-section data were benchmarked in the energy range 1100-4100 keV by comparison to measured spectra from bulk beryllium. The cross-section data are presented in graphical and tabular forms.Ó 2015 Elsevier B.V.

“…Both RBS and EBS are elastic, but as the beam energy increases, the distance of closest approach of the colliding nuclei decreases until the nuclear wavefunctions effectively overlap during the interaction, and the "point charge" approximation which allows the use of the Coulomb potential for RBS is no longer valid. EBS cross-sections can be very complicated functions, but in the last decade an important subset of these have been evaluated [18] by solving Schrödinger's equation for the interaction, using known nuclear data (including nuclear energy levels from gamma spectroscopy) as well as measured EBS scattering cross-sections, which have recently been compiled into a usable database in an IAEA Coordinated Research Project [19].…”

Ion beam analysis (IBA) is a cluster of techniques including Rutherford and non-Rutherford backscattering spectrometry, and particle-induced X-ray emission (PIXE). Recently, the ability to treat multiple IBA techniques (including PIXE) self-consistently has been demonstrated. The utility of IBA for accurately depth profiling thin films is critically reviewed. As an important example of IBA, three laboratories have independently measured a silicon sample implanted with a fluence of nominally 5.1015As/cm2 at an unprecedented absolute accuracy. Using 1.5 MeV 4He+ Rutherford backscattering spectrometry (RBS), each lab has demonstrated a combined standard uncertainty around 1% (coverage factor k=1) traceable to an Sb-implanted certified reference material through the silicon electronic stopping power. The uncertainty budget shows that this accuracy is dominated by the knowledge of the electronic stopping, but that special care must also be taken to accurately determine the electronic gain of the detection system and other parameters. This RBS method is quite general and can be used routinely, to accurately validate ion implanter charge collection systems, to certify SIMS standards, and for other applications. The generality of application of such methods in IBA is emphasised: if RBS and PIXE data are analysed self-consistently then the resulting depth profile inherits the accuracy and depth resolution of RBS and the sensitivity and elemental discrimination of PIXE

The total cross sections of the 12 C(d, energy range using a self-supporting natural carbon foil and detecting the gamma-rays and particles simultaneously. In order to test the validity of the measured gamma-ray producing cross sections, benchmark experiments were performed using kapton foils with two different thicknesses. Both the obtained gamma-and particle production cross section results were compared with data existing in literature, and in the case of (d,p o ) the experimental differential cross-section data were compared also with the theoretical evaluated values.pγ
