摘      要：As radiochemical techniques have an unsurpassed sensitivity, they are best apt to search for, to identify and to determine very small α-decay branches of longer-lived transuranium nuclides. Therefore, we have developed a chemical separation scheme to search for the missing α-decay branch in 239Cm (T1/2≈3 h). Details of the motivation for this experiment and preliminary results from the first experiments are given elsewhere in this report.
