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 spins using the EUROGAM2 array. OXBASH code calculations support the experimental identification of maximum aligned configurations in these isotopes. Empirical 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 een the observed and calculated excitation energy of the I-pi=12(+) level in Te-136 indicates possible admixtures of collective excitations in this nucleus. Clear signs of collective excitations are observed in Xe-138.
