Neutron transfer and flow in reactions between heavy neutron-rich nuclei.

Two Step WKB calcualtions of nucleus nucleus capture were carried out. In our calcualtions we nvestigate the possibility of enhanced capture cross sectins for neutron rich heavy nuclei. The model calculation uses a systematic potential [1] that incorporates the effect of barrier distributions due to excitation and deformation in the entrance channel. Neutron transfer is treated in a semiclassical approximation [2][3]. The transfer form factor used in neutron transfer saturates at an internuclear distance where where neutron can flow freely between the two nuclear centers [4]. \newline \newline [1] K.
