The Tz=-1 nucleus, 58Zn has been identified and its mass measured for the first time. The pion double charge exchange reaction 58Ni(π+, π-)58Zn was used to produce 58Zn and the mass scale was calibrated by means of the reaction 9Be(π +, π-)9C, which has very nearly the same Q-value. The atomic mass excess was found to be -42.295±0.050 MeV.
