The half life of the 7 − isomeric state of the odd-odd 68 Ga nucleus was measured using a particle-γ delayed coincidence technique. The 68 Ga nuclei were produced using the fusion-evaporation reaction 55 Mn( 16 O,2pn) 68 Ga at 55 MeV incident beam energy. The beam was produced by the 8 MV Pelletron accelerator of the Nuclear Physics Open Laboratory of the University of São Paulo. The half life was measured using the Isomeric State Measurement System (SISMEI). The obtained value was 60.83(25) ns, compatible with previous measurements. The 68 Ga excited states were well described with the Large Scale Shell Model using the JUN45 residual interaction.
