Abstract
Excited states in the neutron-rich, N=84 nuclei Sn-134, Te-136 and Xe-138, populated in the spontaneous fission of Cm-248, Were Studied to medium spin s using the EUROGAM2 array. OXBASH code calculations support the experiment al identification of maximum aligned configurations in these isotopes. Empi rical shell model calculations agree with the proposed excitation energy of the neutron h(9/2) excitation in the Sn-132 region. A discrepancy bct it e en the observed and calculated excitation energy of the I-pi=12(+) level in Te-136 indicates possible admixtures of collective excitations in this nuc leus. Clear signs of collective excitations are observed in Xe-138.
