We studied the β-decay properties of neutron-rich ⁸⁵Ga produced in proton-induced fission of ²³⁸U at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. Data consisted of β-γ and β-γ-γ coincidences were collected at the Low-energy Radioactive Ion Beam Spectroscopy Station after high-resolution on-line mass separation. For the first time, the excited states in the N=53 isotone ⁸⁵Ge were established from β-delayed γ decay of ⁸⁵Ga. The level scheme of the N=52 isotone ⁸⁴Ge was improved and includes now 0⁺, 2⁺, (2)⁺, 4⁺, and (0)⁺ states populated in the β-delayed-neutron-γ decay of ⁸⁵Ga. Advanced shell-model calculations were used to analyze experimental data on ⁸⁵Ge and ⁸⁴Ge.
