[Sublimatographic separation of fission products by beta-diketone complexes -fission products chelate complexes in the non-volatile M(beta-diketone)n produced directly by recoil effects].
The sublimatographic separation of volatile beta-diketonate complexes of fission products produced directly by the recoil atoms of fission products under exposure of a mixture of non-volatile M(beta-diketone)n and U-3 (JAERI) on neutron, was carried out. When Ba(acac)2 and K(acac) were used as catcher chelates, both samples did not deposited radioactive chelates and inactive chelates in the inner glass tube. But the volatile Zr (acac)4 chelates were mixed with the samples of Ba(acac)2+U-3 after irradiation, the radioactive chelates deposited together with the inactive chelates of Zr(acac)4 at the same position in the inner glass tube. The nuclides in the deposited zones were mainly 97Zr-97Nb, 91mY, 92Y and 93Y. On the other hand, in the case of Y(Dpm)3 chelates mixed, the nuclides in the deposited zones of the radioactive and inactive chelates were 91mY, 92Y, 97Zr-97Nb, 141Ce and 143Ce. When the volatile Zr(acac)4 chelates were mixed with the sample of Ba(acac)2+U-3 after irradiation, the yield of deposited 97Zr nuclide was directly proportional to the amount of Zr-(acac)4 up to about 5 times against the amount of the irradiated sample.
