Abstract

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 5d 6 6s 2 5 D 4 . The electron affinity of rhenium is determined to be 487.13(51) cm –1 or 60.396(63) meV.
