Microsecond isomers in the very proton-rich {ital N}=82 nuclei {sup 153}Lu and {sup 154}Hf have been identified by {gamma}-ray spectroscopy following mass analysis of {sup 102}Pd +245 MeV {sup 54}Fe reaction products using the Daresbury Recoil Separator. The decays of the isomers, interpreted as ({pi}{ital h}{sub 11/2}){sup n} states, are characterized. Examination of reduced {ital E}2 transition rates between ({pi}{ital h}{sub 11/2}){sup n} states in the {ital N}=82 isotones indicates that the half-filling of the {pi}{ital h}{sub 11/2} subshell occurs just below {ital Z}=71.
