    Abstract

    Neutron-rich, odd-Z nuclei 145La and 147La populated in spontaneous fission of 248Cm were studied using the EUROGAM array. The experiment indicates the presence of similar octupole correlations in the studied La isotopes as found in the barium core nuclei. Alternating-parity structures were found in 145La, indicating enhanced octupole correlations, as observed in 144Ba, while in 147La octupole effects are weakened by alignment phenomena, as seen in the core nucleus 146Ba.
