Isotope yields with a solenoid-based fragment mass analysis system – prospects for exotic isotope studies in the 10≤Z≤30 range

Yields of neutron-rich and other ions in the region of 10≤Z≤30, produced by a 30 MeV/u 136Xe24+ beam on a thick natC target, are presented. The ions were collected and identified with the University of Michigan 7-Tesla solenoid device `BigSolʹ at 1.36 Tm. The yields are sufficient to make feasible gamma- and/or beta-decay studies of lifetimes and nuclear structure at the solenoidʹs focal position, or alternately with the fragments transported away for low-background studies. Small but usable amounts of ions close to or including the most n-rich ions produced anywhere to-date are produced and it is shown that if particle-by-particle identification is not continuously required, that the yields may be increased by over two orders of magnitude.
