The level structure of the N=82 nucleus Xe136 was studied with the inelastic neutron scattering reaction followed by γ-ray detection. A number of the spins and parities were reassigned, and many level lifetimes were determined for the first time using the Doppler-shift attenuation method. New shell-model calculations were also performed using both the full Z=50-82 model space, and a reduced model space including only the 1d5/2 and 0g7/2 orbitals. This new information characterizing Xe136 was used to identify the seniority structure of the low-lying levels and to assign (π0g7/2)υ=04, (π0g7/2)υ=24, (π0g7/2)υ=44, (π1d5/2)(π0g7/2)υ=13, and (π1d5/2)2(π0g7/2)υ=02 configurations to describe all observed states below 2.8 MeV.
