It was believed that the rhenium anion Re- was not stable, just like Mn-. We report the observation of Re- in the laser ablation ion source and the further confirmation via the high-resolution photoelectron spectra of Re-. The ground state of Re- ions is 5d66s2 5D4. The electron affinity of rhenium is determined to be 487.13(51) cm-1 or 60.396(63) meV.
