| Abstract;It is difficult to produce of neutron rich nucleus of heavy actinides. Therefore, many nuclides have not been discovered so far even though they would have long halflife. It is expected that 252Bk has about 10 minutes halflife and decays by .BETA.-delayed fission. The .BETA.-delayed fission is important to clarify fission process. 252Bk could be produced by the reaction248Cm(18O, X)252Bk. In this reaction, many kinds of actinides would be produced at the same time. Chemical separation of 252Bk from other actinides is essential in order to measure 252Bk activity. For an a measurement, no residue is desirable after chemical separation. We chose anion exchange of HNO3-CH3OH system and search the optimum condition for the separation for 252Bk. (author abst.) |
