摘要

<正>The overall separation scheme to obtain a chemically purified Cm sample for the search of an α-decay branch in 239Cm (see for preliminary results) is described in Part Ⅰof this contribution. The Part Ⅱdescribes details of the liquid chromatographic separation of a Cm fraction - modeled with lanthanide (Ln) tracers. The main goal of the scheme was to produce fast, reliably and with a high and controllable yield Cm fractions which are free from unwanted α-activities. This separation scheme was not optimized to separate elements which may strongly interfere in γ-spectroscopic studies.
