Abstract

Angular distributions in the reaction ⁶Li(p, ³He)⁴He have been measured over the energy range 0.5–1.82 MeV. Two particle pick-up theory is used to analyse the results and, with a constant normalisation factor of 0.3, it accounts well for the observations below 1.3 MeV and for the non resonant yield above 1.3 MeV.

However, ERDA allows only the analysis of relatively thin layers, requires smooth surfaces, and gets technically challenging for larger samples or curved surfaces, as is often the case for PFCs. For NRA the 6Li(p,3He)4He reaction has a relatively high cross section at energies above about 1.6 MeV [28–30]. However, the available cross section data for this reaction [31] are inconsistent and at backward angles the energy of the produced 4He is below and the energy of the produced 3He is only marginally above the incident energy due to the low Q-value of the reaction, rendering this reaction only marginally useful if Li films on heavy substrates should be investigated.
Different ion beam analysis techniques for the study of thin lithium-containing layers on top of fusion relevant materials are discussed and compared to each other. Elastic backscattering analysis (EBS) with protons is determined to be one of the most promising techniques and allows measurements of Li layers with thicknesses from ∼100 nm up to ∼600 μm, as shown by SIMNRA simulations. The best sensitivity for thin films (∼100 nm) can be achieved using 4 MeV protons with 170° scattering detection angle for layers on Mo and W substrates, and 2 MeV for C substrates. Experimentally EBS measurements were successfully tested for Li films with thicknesses from ∼50 nm up to ∼400 nm after air exposure. The Li films become strongly inhomogeneous and require averaging over multiple measurements in nearby areas. This necessitates averaging over multiple nearby measurement points, and limits the overall precision of the measurement.
Low-energy cross sections for the 6Li(p, 3He)4He reaction
1989, Nuclear Physics, Section A
Differential and total cross sections for the ⁶Li(p, ³He)⁴He reaction at proton energies between 120 keV and 505 keV have been measured. The ⁶Li+p elastic scattering also has been measured and used as a cross section standard. The total cross section shows a weak structure at E_p ∼ 400 keV. The astrophysical S-function defined as σ_tot =[S(E)/E] exp (−2 πη -gE) is well represented by a constant value 2.97 ±0.03 MeV · b.
