Sj. Zhu et al., OCTUPOLE DEFORMATION IN BA-142,BA-143 AND CE-144 - NEW BAND STRUCTURES IN NEUTRON-RICH BA-ISOTOPES, Physics letters. Section B, 357(3), 1995, pp. 273-280
New, high spin band structures are established for the neutron-rich nu
clei Ba-142,Ba-143,Ba-145,Ba-147, and Ce-144, and levels of Ba-144,Ba-
146 extended to higher spins from the study of gamma-gamma and gamma-g
amma-gamma coincidence studies in spontaneous fission. Alternating par
ity sequences connected by strong electric dipole transitions are iden
tified in Ba-142,Ba-143 and Ce-144 but not in Ba-145,Ba-147 to confirm
theoretical predictions of stable octupole deformation for N = 86.
