摘　　要：用核化学技术研究了８．２、１２．１、１６．２、２０．０和２４．２ＭｅＶ／ｕ４０Ａｒ离子和１９７Ａｕ相互作用中，反应余核的激发函数和碎片的反冲性质。根据反冲性质讨论了各种反应余核可能的生成机制。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.
