[en] Spectroscopic data for all nuclei with mass number A=136 have been evaluated and the corresponding level schemes from radioactive decay and reaction studies are presented. No excited states are known in 136In, 136Eu, or 136Gd and 136Tb remains unidentified. Discrepancies between experiments on isomeric decays in 136Sb and 136La suggest the need for futher experimental investigation. The decay of 136Eu has only been observed in a mixed source. The energy of the 17.5 s isomer in 136Cs was determined since the last evaluation, however, the branching ratio remains unknown. This work supersedes the earlier full evaluation of A=136 by A.A. Sonzogni (2002So05), and benefited tremendously from all previous evaluations of A=136.
