The β-decay half-lives of 128–130Cd have been measured with the newly commissioned GRIFFIN γ-ray spectrometer at the TRIUMF-ISAC facility. The time structures of the most intense γ rays emitted following the β decay were used to determine the half-lives of 128Cd and 130Cd to be T1/2=246.2(21)ms and T1/2=126(4) ms, respectively. The half-lives of the 3/2+ and 11/2− states of 129Cd were measured to be T1/2(3/2+)=157(8) ms and T1/2(11/2−)=147(3) ms. The half-lives of the Cd isotopes around the N=82 shell closure are an important ingredient in astrophysical simulations to derive the magnitude of the second r-process abundance peak in the A∼130 region. Our new results are compared with recent literature values and theoretical calculations.
