Abstract

Absolute differential cross sections for the scattering of protons by deuterium have been measured at eight proton energies from 1.000 to 10.04 MeV for angles from 10.50° to 166.00° in the centre-of-mass system. The median uncertainty of all measurements is ±0.6%.

These incorrect data are also included in Ref. [56]. As long as no further data are available, the suggested cross sections for use at backward angles are those from Ref. [52] and the data set based on the absolute values by Langley [49,55]. The two most recent publications [53,54] present a few cross sections data points between 3.1 and 3.7 MeV and between 0.4 and 1.0 MeV for angles below 135°.
Ion Beam Analysis (IBA) is a set of material characterization techniques using energetic ion beams. IBA provides information about composition and the depth profile of elements in the near-surface layers of a sample, from the energy spectra of backscattered primary particles, recoils, nuclear reaction products or emitted γ-radiation. All IBA methods presuppose knowledge of the differential cross-section data however, only for strict Rutherford scattering is the cross-section known exactly. In order to address the data needs of the IBA community, the IAEA initiated the Coordinated Research Project (CRP) “Development of a Reference Database for Ion Beam Analysis” in 2005 which will conclude in 2010. The project focuses on the measurement, assessment, evaluation and benchmarking of elastic scattering and reaction cross sections. Data measured in this work have been incorporated in the IBANDL database (http://www-nds.iaea.org/ibandl/), whereas the evaluated cross-sections (calculated from the fit to the data of a nuclear model) are made available to the community through the on-line calculator SigmaCalc (http://www-nds.iaea.org/sigmacalc/).
A summary of the results of the CRP activity is presented, and ways to further develop nuclear data for IBA are indicated. In particular, a newly proposed CRP devoted to particle induced gamma-ray emission is described.
Measurement of the D(p,p)D cross section at laboratory backward angles of 151° and 167°

While the general trend suggests a slight decrease in cross sections with increasing beam energy, the difference in values between 151° and 167° laboratory angles are statistically insignificant. Scherr et al. data were measured at 150° laboratory angle [1], Kocher and Clegg data were measured at 153° laboratory angle [2], and Langley’s data were measured at 170° laboratory angle. Both Scherr’s data and Kocher’s data were measured from a D2 gas target, while Langley’s data were measured from a thin film of (800 nm) ErD2 on Kovar substrate.
Elastic backscattering spectrometry was completed to determine proton–deuterium scattering cross sections for the D(p,p)D reaction. An ErD₂ thin film on a substrate of Kovar was used for the measurements with a proton beam at energies of 1.9–3.0 MeV and laboratory scattering angles of 167° and 151°. Within the energy range used, the measured differential scattering cross section (mb/sr) showed no significant angular dependence between these two angles, and only a slight dependence on beam energy. However, the laboratory cross section to Rutherford ratios (σ/σ_R) increased linearly with beam energy at both angles; as beam energy increased from 1.9 to 3.0 MeV, the cross section ratio (σ/σ_R) increased from 83.4 to 185.5 at 151° and from 548.5 to 1178.4 at 167°. Our data agreed reasonably well with a set of literature values obtained at laboratory scattering angles of 150°, 153°, and 170°. Finally, we have attempted to clarify confusion in the literature resulting from conversions between different angular systems as well as conversions between measured cross section values and cross section to Rutherford ratios.
Indirect study of 19Ne states near the 18F + p threshold
2007, Nuclear Physics A
The early $E ⩽ 511 keV$ gamma-ray emission from novae depends critically on the ${}^{18}F (p, α) {}^{15}O$ reaction. Unfortunately the reaction rate of the ${}^{18}F (p, α) {}^{15}O$ reaction is still largely uncertain due to the unknown strengths of low-lying proton resonances near the ${}^{18}F + p$ threshold which play an important role in the nova temperature regime. We report here our last results concerning the study of the $d ({}^{18}F, p) {}^{19}F (α) {}^{15}N$ transfer reaction. We show in particular that these two low-lying resonances cannot be neglected. These results are then used to perform a careful study of the remaining uncertainties associated to the ${}^{18}F (p, α) {}^{15}O$ and ${}^{18}F (p, γ) {}^{19}{Ne}$ reaction rates.
Ion beam analysis methods in the studies of plasma facing materials in controlled fusion devices

Another reaction for deuterium analysis, D(p,p)D [18,19], is cheaper than the one involving 3He, but depth profiling is limited.
Application of ion beam analysis techniques in the studies of material transport and fuel inventory in the controlled fusion devices is exemplified. Enhanced proton scattering on the carbon isotopes ¹²C(p,p)¹²C, ¹³C(p,p)¹³C and secondary ion mass spectrometry allowed for determination of carbon erosion and re-deposition on the wall components following the experiments with a tracer (¹³CH₄) injection into the plasma edge at the TEXTOR tokamak. For the assessment of the deuterium fuel accumulation in the plasma facing components depth profiling by means of nuclear reaction analysis, ³He(d,p)⁴He, was performed. Advantages and limitations of those nuclear methods in solving experimental problems are addressed.
