Abstract Neutron-rich, odd-{ital Z} nuclei {sup 145}La and {sup 147}La populated in spontaneous fission of {sup 248}Cm 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 {sup 145}La, indicating enhanced octupole correlations, as observed in {sup 144}Ba, while in {sup 147}La octupole effects are weakened by alignment phenomena, as seen in the core nucleus {sup 146}Ba. {copyright} {ital 1996 The American Physical Society.}
