Abstract

A new separation scheme is presented for the isolation of Nd fractions highly purified from adjacent lanthanides, especially Ce and Pr, in preparation to demanding isotope ratios applications, e.g. determination of ¹⁴²Nd/¹⁴⁴Nd, or measurement of ¹⁴³Nd/¹⁴⁴Nd on very small samples by using NdO⁺ ion beams.
