N2 - The germanium-vacancy center in diamond is actively studied because it is promising in various quantum-optical and quantum-informational applications. There is not much information about the paramagnetic neutral germanium-vacancy center (GeV0) in triplet spin state. In this work, the spin relaxation of the GeV0 is studied by pulse electron paramagnetic resonance (EPR) technique at low temperatures. It is shown that spin-lattice and spin-spin relaxation times for the GeV0 are shorter than corresponding times for the neutral silicon-vacancy center. The Orbach mechanism of spin-lattice relaxation dominates for the GeV0 center in the temperature range 80–110 K (activation energy Ea = 39(6) meV).
