In these calculations, the pre-equilibrium effects have been investigated. The pre-equilibrium calculations involve the geometry dependent hybrid model and hybrid model. A comparison with theoretical calculations (ALICE/ASH) has been performed and the empirical formulas for the He-4-emission cross sections produced at 62 MeV proton energy have been derived.eninfo:eu-repo/semantics/closedAccessHelium-4 emission spectraPre-equilibrium reactionsGeometry dependent hybrid modelHybrid modelArticle301343810.1007/s10894-010-9339-22-s2.0-79951515674Q2WOS:000286211300007Q3
