Excited levels in Cs-139: populated in spontaneous fission of Cm-248, have
been studied by means of prompt gamma spectroscopy, using the EUROGAMM 2 ar
ray. New level scheme of Cs-139, different from the one proposed recently,
has been established. To confirm the new scheme, additional study of Cs-139
has been performed; where gamma-rays following beta-decay of Xe-139 to Cs-
139 have been measured at the mass separator OSIRIS.
