Fusion and transfer cross sections of 3He induced reaction on Pt and Au in energy range 10–24.5 MeV

Abstract

In experiments performed by accelerated ion 3He-beam irradiated gold and platinum targets on the cyclotron U-120M of the Nuclear Physics Institute of the Czech Academy of Sciences, Řež, reactions of complete and incomplete fusion and nucleon transfer reactions in the 3He energy range from 10 to 24.5 MeV have been investigated. To determine the yield of the nuclides resulting from the nuclear reaction, the activation technique has been used. The obtained data are analyzed using models based on statistical calculations and compared with similar results for other light stable particles. Transfer reactions with positive Q values have relatively high cross sections in the energy range below the Coulomb barrier. These cross sections continue to grow with increasing 3He energy, and, in the case of capturing neutron from target nucleus by a nucleus of 3He, the excitation functions of these reactions reach their maximum almost at the Coulomb barrier of the reactions.
