Abstract

Electron affinities (EAs) of many lanthanide elements still remain unknown due to their complicated electronic structures and relatively low EA values. In the present work, we utilized the slow-velocity map-imaging method combined with an ion trap to resolve conundrums. The EA values of praseodymium, neodymium, and terbium are determined to be 881.0(37)\phantom\rule0.16em0excm^\ensuremath-1 or 0.109 23(46) eV, 786.3(26)\phantom\rule0.16em0excm^\ensuremath-1 or 0.097 48(31) eV, and 1059.1(64)\phantom\rule0.16em0excm^\ensuremath-1 or 0.131 31(79) eV, respectively. We also observed several excited states of Pr, Nd, and Tb anions.
