Dipole strength distributions of the stable odd-mass N=82 isotones La-139 and Pr-141

The low-lying dipole strength distributions of the odd-mass isotopes 139La and
141Pr were studied in nuclear resonance fluorescence experiments using bremsstrahlung beams. Excited states were observed at excitation energies up to 4 MeV. Spectroscopic information was obtained on excitation energies, decay widths, decay branching ratios, and transition probabilities. The states belonging to the [[2+⊗3−]⊗ particle/hole] coupling were a special focus, and the results are compared with other stable odd-mass nuclei at or near the N=82 shell closure.
