Bk and Cf chromatographic separation and 249Bk/248Cm and 249Cf/248Cm elemental ratios determination by inductively coupled plasma quadrupole mass spectrometry

► Bk and Cf separation by Ionic Chromatography in a 248Cm irradiated sample. ► This separation was performed by ICP-QMS/IC coupling. ► Isotope ratio composition of the purified fractions by ICP-QMS. ► With work we contribute more precise data for actinide neutron capture cross-sections
