We measured the half-life of Ga 66   by observing positrons from the β +   branch to the ground state of Zn 66   with a superconducting Wu-type beta spectrometer. Our result is t 1/2 =9.304(8)hours  , which is the highest-precision measurement to date and disagrees with the Nuclear Data Sheets (NDS) value by over 6σ  .
