Abstract

We identified in this experiment two muon configurations in Lu2O3, the oxygen-bound (O−Mu+) ground state and a metastable (energy barrier 0.7(3) eV) atom-like excited state. These configurations are partially not formed immediately after implantation but somewhat delayed due to the requirement of a lattice rearrangement around the muon. These rearrangement processes occur on a timescale of ns to μs and are thus observable in μSR experiments. A special role plays a fairly long-lived (ns to μs) transition state as an intermediate step in the reaction process.
