A specially prepared Si/He thin solid film was investigated as a suitable target for experimental studies on nuclear reactions involving \(^4\)He targets. For that purpose, the elastically scattered \(^4\)He recoil coming from the reaction \(^6\)Li + \(^4\)He at incident energy of 5.5 MeV was measured. The differential cross section of \(^6\)Li on \(^{4}\)He has been found to be fully consistent with previous measurements in the literature. The prospective advantages of using these solid He targets in experiments at radioactive beam facilities are discussed.
