A multiparticle spin-trap isomeric state having a half-life of 179(4) ns and lying 2601 keV above the yrast
10
+
state in
156
Lu
has been discovered. The
156
Lu
nuclei were produced by bombarding isotopically enriched
106
Cd
targets with beams of
58
Ni
ions, separated in flight using the gas-filled separator RITU and their decays were measured using the GREAT spectrometer. Analysis of the main decay path that populates yrast states observed previously suggests a spin-parity assignment of
19
−
for the isomeric state, which is consistent with isomeric states identified in the
N
= 85 isotones. Comparison with other decay paths in
156
Lu
indicates that the

compared with its odd-odd isotones.
