New experimental information has been obtained on the {mu}s isomeric cascade in the very neutron-rich {sup 136}Sb using {gamma}-ray and conversion-electron spectroscopy at the Lohengrin mass spectrometer of the Institut Laue-Langevin. Two new transitions have been observed and their multipolarities determined, resolving the question of the origin of the isomerism. The new level scheme is in good agreement with predictions of a realistic shell-model calculation. The isomeric state is tentatively assigned a spin and parity of 6{sup -} and a proposed {pi}g{sub 7/2}{nu}(f{sub 7/2}){sup 3} dominant configuration.
