Abstract
The half-life of **6**0Fe has been measured to be T// one-half equals (1. 49 plus or minus 0. 27) multiplied by 10**6 a, significantly longer than the one previous measurement of Roy and Kohman which reported a value of 3 multiplied by 10**5 a, uncertain by a factor of 3. The present value was obtained from measurements of specific activity and radioisotope concentration in a material produced by spallation of copper with 192 Mev protons. **6**0Fe/Fe ratios in the range of 10** minus **8 were measured with the Argonne FN tandem-superconducting linear accelerator system in conjunction with an Enge split-pole spectrograph. The specific activity of **6**0Fe in Fe was measured through the grow-in of the 1. 332 Mev gamma-ray line of the **6**0Co daughter activity.
