Partial decay schemes for the very neutron-rich nuclei ¹⁴²,144Ba and ¹⁴⁶Ba have been determined by the study of {γ}-{γ} coincidences in ²⁵²Cf fission fragments. Interlaced positive- and negative-parity levels connected by fast electric dipole transitions are observed in ¹⁴⁴Ba and ¹⁴⁶Ba above spin 7{}. This is similar to the situation in some light actinide nuclei, where the data have been interpreted in terms of reflection-asymmetric shapes.
