Abstract: Abstract: Masses of the radioactive isotopes 62Ga, 62Zn and 62Cu have been measured at the JYFLTRAP facility with a relative precision of better than . A value of () keV for the superallowed decay of 62Ga is obtained from the measured cyclotron frequency ratios of 62Ga 62Zn, 62Ga 62Ni and 62Zn 62Ni ions. The resulting -value supports the validity of the conserved vector current hypothesis (CVC). The mass excess values measured were () keV for 62Ga, () keV for 62Zn and () keV for 62Cu.
