Automated system for selective fission product separations applied to the study of /sup 113 -115/Pd
A microcomputer-controlled radiochemical separation system has been developed for the isolation and study of fission products with half-lives of greater than or equal to 10 s. The system, based upon solvent extraction with three centrifugal contactors coupled in series, provides both rapid and highly efficient separations with large decontamination factors. This automated system was utilized to study the radioactive decays of /sup 113 -115/Pd via solvent extraction of the Pd-dimethylglyoxime complex from /sup 252/Cf fission products. As a result of this effort, ..gamma.. rays associated with the decay of approx. 90-s /sup 113/Pd, 149-s /sup 114/Pd and 47-s /sup 115/Pd have been identified. The assignment of masses to each of these Pd radioactivities has been confirmed from observation of the growth curves of their respective Ag daughters. In addition, previously unreported Ag ..gamma.. rays have been assigned; one to the decay of 69-s /sup 113/Ag, and two to the decay of 19-s /sup 115/Ag.
