The
α
-decay branch of the
πh
11
/
2
isomer in
164
Ir has been identified using the GREAT spectrometer. The
164
Ir
nuclei were produced using the
92
Mo(

,p

n
)
164
Ir reaction and separated in flight using the recoil ion transport
unit (RITU) gas-filled separator. The measured
α
-decay energy of 6880
±
10 keV allowed the excitation of the
πh
11
/
2
state in
160
Re to be deduced as 166
±
14 keV. The half-life of
164
Ir was measured with improved precision
to be 70
±
10
μ
sandan
α
-decay branching ratio of 4
±
2% was determined. Improved half-life and branching
ratio measurements were also obtained for
165
Ir, but no evidence was found for the ground-state decays of either
164
Ir or
165
Ir.
