Survival probability (a), charge state fractions (b) and the product of the fully-stripped fraction, the survival probability and the target thickness (c) of 181^Er as a function of target thickness.

Caption

The target thickness was optimized to maximize the yield of neutron-rich rare-earth isotopes. The effects of charge state distribution and reaction loss due to secondary reactions were considered. As a result, an optimal thickness of 4 g/cm2 for beryllium was adopted to estimate the production of neutron-rich isotopes in the rare-earth region via fragmentation of 198Pt.
