title: Radiochemical separations by the ring-oven technique-IV The system (144)Ce/(144)Pr.
abstract: By using filter papers impregnated with a manganese oxide hydrate having an average oxidation number of + 3, it is possible to separate (144)Pr from (144)Ce rapidly by the ring-oven technique. With 0.06-0.07M trichloracetic acid as wash-solution, the daughter nuclide can be concentrated in the ring zone with 80-90% yield and decontamination factors > 10(3). The half-life of the separated (144)Pr was found to be 17.60 +/- 0.05 min. The behaviour of other fission nuclides under the same conditions was also investigated.
