The low-lying levels in 127La have been studied through the β-decay of 127Ce (T1/2 = 29 s) produced by bombarding a natMo target with a 185-MeV 35Cl beam. Reaction products were on-line mass-separated, and γ-ray singles and γ-γ coincidence measurements were performed. Conversion electrons were also measured and multipolarities of transitions have been derived. The half-life of the 210.9-keV level was determined to be (1.9 ± 0.3) ns by the β-γ delayed coincidence technique. The level scheme obtained has been compared with calculations based on the Nilsson model.
