Analysis of Cf-252 recent spontaneous-fission gamma data from Gammasphere h
as enabled the discovery of transitions in Ba-139 in coincidence with those
of its Molybdenum fission partner. A new level scheme going up to approxim
ate to5 Mev includes 11 new transitions and 10 new levels. We make analogie
s with the 83-neutron isotone Te-135 and discuss possible configurations in
the spherical single-particle shell model. We suggest a band as a possible
magnetic rotation band of the type treated by tilted-axis cranking theory.
