The reactions of complete and incomplete fusion, along with nucleon transfer reactions in the range of 3 He energies from 10 to 24.5 MeV, are investigated by irradiating gold and platinum targets with an accelerated 3 He ion beam on the U-120M cyclotron at the Institute of Nuclear Physics, Czech Academy of Sciences, Řež. Activation is used to determine the yield of nuclides resulting from nuclear reactions. The γ-activity induced in the targets is measured using a with high-resolution HPGe detector. Despite the low binding energy of 3 He and the reactions with positive Q values, the measured cross sections of fusion reactions exhibit no specific features, compared to reactions conducted using beams of other light stable particles. Transfer neutron reactions in the subbarrier energy region have relatively high cross sections. These cross sections continue to grow as the energy of 3 He rises. When a neutron is captured by a nucleus of 3 He, the cross sections of these reactions reach their maximum values in the Coulomb barrier region.
