【Abstract】 The excitation functions and recoil characteristic of the target fragments have been studied from the interaction of gold with 8 2,12 1,16 2,20 0 and 24 2 MeV/nucleon 40 Ar ions using nuclear chemical techniques.The possible formation mechanisms for various reaction residues are discussed on the basis of the recoil characteristic.Variation of the cross sections from heavy target residues with energies of 40 Ar ions is indicated.更多还原
