New inverse quasifission mechanism to produce neutron-rich transfermium nuclei

Based on time-dependent Hartree-Fock theory, a new inverse quasifission mechanism is proposed to produce neutron-rich transfermium nuclei in the collision of prolate deformed actinides. Calculations show that the collision of the tip of one nucleus with the side of the other results in a nucleon flux toward the latter. The roles of nucleon evaporation and impact parameter, as well as collision time, are discussed.
