英文摘要	Within the framework of the dinuclear system model, the reaction mechanism for producing the proton-rich actinide isotopes Z = 93-100 near the proton drip line is thoroughly investigated in the fusion reactions with Mg-24, Si-28, S-32, Ar-36,Ar-40, and Ca-40 bombarding the target nuclei Ta-181, W-180, Re-185, Os-184, Ir-191, Pt-190, Au-197, Hg-196, Tl-203, Pb-204, and Bi-209, and in the multinucleon transfer reactions with proton-rich radioactive beams Cu-59, As-69,Nb-90, Tc-91, Rh-94, Sn-105,Sn-110, and Xe-118 on U-238 near Coulomb barrier energies. The production cross sections of new proton-rich isotopes in the fusion-evaporation reactions and fragment yields in the multinucleon transfer reactions are estimated systematically and compared in both reaction mechanisms, in which a statistical approach is used to describe the decay process of excited nuclei. A dynamical deformation is implemented in the model in the dissipation process. It is found that charged particle evaporation channels (alpha and proton) dominate in the decay process of proton-rich nuclides. The fusion-evaporation reactions are favorable to produce the new neutron-deficient actinide isotopes. The total kinetic energies and angular spectra of primary fragments in multinucleon transfer reactions are strongly dependent on colliding orientations and incident energies.
