The 70Ga nucleus has been investigated via the 68Zn(α, pnγ)70Ga reaction at Eα = 23-40 MeV. The level scheme has been established by means of relative yield functions, electronic timing measurements, prompt and delayed coincidences and angular distributions of the emitted γ rays. The assignations of spins up to 9+ to levels up to 2.9 MeV excitation energy specify the components of the (νlg9/2) subshell
