In this paper, the differential cross-section for forward recoiling H-1 with He-4 ions has been determined in the energy range of 1.6-6.0 MeV at a laboratory angle of 30 degrees. A film of similar to 54 nm TiHx on the Si substrate with an overlayer of similar to 7 nm Ta on the TiHx foil was used as the target, and hydrogen loss of the target due to ion bombardment can be fully ignored (<0.1%) through the whole measurement. A method of relative determination for the cross-section measurement was employed to be free from absolute determination of hydrogen content in the target as well as absolute measurements of beam dose and solid angles of the detectors. The uncertainty of the determination is less than 5.2%. (C) 2014 Elsevier B.V. All rights reserved.
