We measure half-lives of the ground state of 184Re and an isomer in 164Ho, which are populated by (γ ,n) reactions with laser Compton scattering (LCS) γ-ray source at NewSUBARU. These neutron-deficient isotopes are located on nucleosynthesis flows of the supernova γ process. The measured half-life of 35.4 ± 0.3 d for 184Re is shorter than the previous half-life of T1/2 = 38.0 ± 0.5 by about 7%. The half-life of the 164Ho isomer is 36.4 ± 0.3 min. This is about 3% shorter than a recommended value T1/2 = 37.5 +1.5 −0.5 min. These results indicate that half-lives of all unstable nuclei near the β stability line may be not robust and that the LCS γ-rays are useful for precise determination of the half-lives.
