Abstract: | Recent efforts to produce and separate neutron-rich rare
isotopes in peripheral collisions below the Fermi energy are
presented. The experiments have been performed at the Cyclotron
Institute of Texas A&M University employing beams from the K500
Superconducting Cyclotron. Two magnetic separators were used: the
MARS recoil separator and the Superconducting Solenoid Line (BigSol
Line). An enhanced production of neutron-rich nuclides in comparison
with high-energy fragmentation mechanisms has been observed and
attributed to the role of the N/Z and the nuclear periphery of the
target. From a practical viewpoint, these reactions below or around
the Fermi energy offer a novel way to access very neutron-rich rare
isotopes. The experience obtained in the production of rare isotope
beams (RIB) below the Fermi energy will be exploited in the ongoing
RIB upgrade of the Cyclotron Institute that will involve production,
stopping and reacceleration of rare isotopes. |
