“…In both cases, an accurate knowledge of the elastic scattering cross sections for the incident beam interaction with the tritium or helium is required. In our previous work, the cross sections for the interaction of p with T in the energy range of 1.6-3.6 MeV and at an angle of 165° [4] has been measured, since very little data of interest from literature [5,6] exist in the energy range 1-3 MeV, and at larger scattering angles, for application of the elastic backscattering technique. Moreover, the interaction of p with He in almost the same energy range and for the same scattering angle [7] has been studied by employing a high heliumcontent titanium (Ti) target, prepared by direct current (DC) magnetron sputtering [8].…”
