Abstract
An analysis of both positive- and negative-parity states of the odd-neutron Ba and the odd-proton La transitional isotopes (N<82) within the framework of the proton-neutron interacting boson-fermion model (IBFA-2) is presented. Energy spectra, electromagnetic properties, isotope shifts and one-nucleon transfer spectroscopic strengths for odd-mass Ba and La isotopes are compared with experiment. Generally good agreement is obtained with a restricted number of adjusted parameters. Some predictions on the properties mentioned above are presented for nuclei for which no experimental data are available.
