We measured the half-life of {sup 66}Ga by observing positrons from the {beta}{sup +} branch to the ground state of {sup 66}Zn with a superconducting Wu-type beta spectrometer. Our result is t{sub 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 6{sigma}.
