Fission gamma spectra and levels in Ba-139 Academic Article uri icon


  • Analysis of 252Cf recent spontaneous-fission data from Gammasphere has enabled the discovery of transitions in 139Ba in coincidence with those of its Molybdenum fission partner. A new level scheme going up to 5 Mev includes 11 new transitions and 10 new levels. We make analogies with the 83-neutron isotone 135Te 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.
