High spin states of
134 Sb,134,135 Te,135,136 I,137 Xe and139 Ba near132 Sn are reanalysed in order to search for octupole phonon vibrational states. New spins and parities are tentatively assigned to the 2203.9 keV state in137 Xe and the 1976.6 and 2091.7 keV states in139 Ba from the state energy plots of the N = 82 and 83 nuclei. High spin states of134 Sb,134,135 Te,135,136 I,137 Xe and139 Ba connected by E1, E3/M2 and E3 transitions are proposed, for the ?rst time, as zero-, one- and two-phonon octupole vibrational (POV) states. One- and two-POV states in134 Sb and135 Te are built on a 7- (πg7/2 υf7/2 ) state and a1 9/2- (υf7/2 ⊗61 + ) state, respectively. One-POV states built on the 19/2- (υf7/2 ⊗61 + ) and the 21/2- (υh9/2 ⊗62 + ) states coexist in137 Xe. Then, one- and two-POV states in139 Ba are built only on the 21/2- (υh9/2 62 + ) state. One- and two-POV states in134 Te are built on the 62 + state with some mixing with the 61 + state. [ABSTRACT FROM AUTHOR]- Published
