摘要
The activities of protactinium were produced by the multi-nucleontransfer reactions in bombardment of the natural uranium with 60 MeV/nucleon 1sOions. A simple, relatively fast radiochemical procedure was used for extraction sep-aration of protactinium from the uranium and a variety of reaction products using1-phenyl-3-methyl-4-benzoyl-5-pyrazolone and tri-iso-octylamine as extractants. Theγ ray spectrum of the separated protactinium fractions showed that the protactiniumcould be separated from all of the main impurity elements. The decontaminationfactors of the uranium and the main reaction products produced in the reaction aregiven.
The activities of protactinium were produced by the multi-nucleon transfer reactions in bombardment of the natural uranium with 60 MeV/nucleon 18O ions. A simple, relatively fast radiochemical procedure was used for extraction separation of protactinium from the uranium and a variety of reaction products using l-phenyl-3-methyl-4-benzoyl-5-pyrazolone and tri-iso-octylamine as extractants. The 7 ray spectrum of the separated protactinium fractions showed that the protactinium could be separated from all of the main impurity elements. The decontamination factors of the uranium and the main reaction products produced in the reaction are given.
