A reaction products mass separator (RPMS) has been used to separate, by the ratio of mass to charge, the reaction products from the collisions of light, intermediate energy (appr. E/A = 30 MeV) nuclei with various targets. The decay modes of the separated nuclei were then studied in a low background environment. Measured in the first experiments with this device were the previously unknown lifetimes of 14Be(4.2(7)ms) and 17C (202(17)ms), and the β-branching ratios for the decay of 9C . The results are compared to shell-model calculations in order to understand the structure of the nuclei involved.
