[en] An efficient way to produce the neutron-rich nuclei in the mass range of 70< A<170 may be achieved via neutron induced fission in uranium ²³⁸U. Depending on the incident neutron energy, the target size and its constituents, it might be also possible to increase this production rate by the secondary neutrons from primary fissions. A few different methods for producing neutrons and their induced fissions following the Be(d,xn) reactions are investigated within the SPIRAL Phase-II project at GANIL. Density, size and material contents of the production target as well as energy of the incident deuteron beam are the major parameters of interest. The production of neutron-rich isotopes presented seems to be very promising if compared to already existing or planned different RIB facilities. (author)
