Production of neutron-rich nuclides and radioactive beams by intermediate energy 238 U fission

Artikel i vetenskaplig tidskrift, 1997

The yields of neutron-rich fission fragments from the interaction of 20 MeV/nucleon 238U with 208Pb have been measured. The production mechanism of these fragments is consistent with sequential fission following a quasielastic or deep inelastic collision. Substantial yields of very n-rich fragments are observed. The importance of these data for generation of n-rich radioactive beams by fission of intermediate-energy projectiles is discussed.
