In this work microsecond isomers in {sup 130,132}Te and {sup 134}Xe are investigated. These nuclei are produced by thermal neutron induced fission of {sup 239}Pu and {sup 241}Pu. The detection is based on time correlation between fission fragments selected by the LOHENGRIN spectrometer at ILL (Grenoble) and the {gamma} rays or conversion electrons from isomers. The 10{sup +}{yields}8{sup +} isomeric transition of {sup 132}Te and {sup 134}Xe was measured for the first time and the half-life of the analogous transition in {sup 130}Te was remeasured. The systematic behavior of the B(E2) values of this isomeric transition is studied in Sn, Te, Xe, and Ba isotopes close to {sup 132}Sn. A simple mechanism is proposed to explain the strong increase in the B(E2) strengths from the Sn to the Te isotones.
