Abstract

Short-lived, neutron-rich isotopes of the rare earth elements La, Ce and Pr have been studied by the means of a continuous solvent extraction separation method (SISAK). Half-lives, energies and relative intensities are reported for γ-rays attributed to 40 ± 3 sec 144La, 20 ± 5 sec 145La, 11 ± 1 sec 146La, 58 ± 3 sec 147Ce, 45 ± 5 sec 148Ce and 9·1 ± 0·4 sec 150Pr. Indirect evidence for the isolation of ⪆5 sec 149Ce and 5–10 sec 150Ce is also presented along with upper half-life limits of 5 sec for 147La and 148La.
