Besides fundamental interest to underlying reaction mechanisms, multinucleon transfer (MNT) reactions and quasifission (QF) processes have been attracted much interest as a useful means to produce neutron-rich heavy nuclei whose production is difficult by other methods. [1,2] To develop our understanding of microscopic reaction mechanisms and to predict optimal conditions for producing objective nuclei, we have studied MNT and QF processes employing the time-dependent Hartree-Fock (TDHF) theory. In Ref.[3], we showed that TDHF provides reasonable cross sections in an accuracy comparable to the successful theories based on, e.g., GRAZING or Langevin calculations. Recently, we have extended our application to MNT associated with QF processes in collisions of heavy nuclei. In the seminar, I will show how TDHF works in describing MNT and QF processes in heavy systems taking 64Ni+238U reaction as a typical example. Then, I will present my personal view of our studies which are expected to be feasible in near future. [1] C.H. Dasso, G. Pollarolo, and A. Winther, Phys. Rev. Lett. 73, 1907 (1994). [2] V.I.
