The electron affinity (EA) of praseodymium (Pr) has been measured using laser photodetachment electron spectroscopy. The EA of Pr(4I9/2) was determined to be 0.962±0.024 eV. The data also show that Pr- has at least one bound excited state with a binding energy of 0.866±0.018 eV relative to the ground state of the Pr atom. The present experimental measurements are compared to a recent calculation of the electronic structure of Pr-.
