Abstract: • Differential cross section measurements of the 7 Li( 3 He, p 0 ) 9 Be, 7 Li( 3 He, p 2 ) 9 Be, and 7 Li( 3 He, d 0 ) 8 Be reactions from 2 to 3.919 MeV at a measurement angle of 135°. • Differential cross section measurements of the 7 Li( 3 He, d 0 ) 8 Be reaction from 2 to 3.919 MeV at a measurement angle of 135°. 7 Li areal density measurement using the 7 Li(p, α) 4 He reaction at 2 MeV and a measurement angle of 150°. The use of lithium in plasma facing components (PFCs) for fusion reactors is increasingly more prominent due to its ability to enhance plasma performance and potential to protect the underlying high-Z PFCs. In order to use nuclear reaction analysis (NRA) to investigate lithium depth profiles in fusion relevant experiments such as hydrogen retention in lithiated PFCs, there is a need for experimental measurements of the cross section of the reactions of interest over a wide range of energies and in a scattering angle in which the differential cross sections of other relevant species, such as deuterium and oxygen, have been measured. In this paper we report the differential cross sections of the 7 Li( 3 He , p 0 ) 9 Be, 7 Li( 3 He , p 2 ) 9 Be, and 7 Li( 3 He , d 0 ) 8 Be reactions from 2 to 3.919 MeV at a measurement angle of 135°. The measurements were performed on a lithium fluoride film target with the 7 Li areal density determined using the 7 Li(p , α ) 4 He reaction at 2 MeV and 150°.
