New information on excited states below the µs isomer in $^{136}$Sb

Abstract : New experimental information has been obtained on the µs isomeric cascade in the very neutron-rich 136Sb 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- and a proposed pig7/2nu(f7/2)3 dominant configuration.
