Abstract We report the high-resolution photoelectron spectra of negative vanadium ions obtained via the slow-electron velocity-map imaging method. The electron affinity of V was determined to be 4255.9(18) cm -1 or 0.527 66(20) eV. The accuracy was improved by a factor of 60 with regard to the previous measurement. The fine structure of V - was well resolved: 35.9(11) ( 5 D 1 ), 103.8(12) ( 5 D 2 ), 204.17(74) ( 5 D 3 ), and 330.58(40) cm -1 ( 5 D 4 ) above the ground state 5 D 0 , respectively.
