[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.
