The electron affinity of thulium has been measured using laser photodetachment electron spectroscopy. The electron affinity of Tm(2F7/2) was determined to be 1.029\ifmmode±\else\textpm\fi0.022eV. The data also show that Tm^\mathrm\ensuremath- has at least one bound excited state with a binding energy of 0.979\ifmmode±\else\textpm\fi0.017eV relative to the ground state of the thulium atom. The present experimental measurements are compared to a recent calculation of the electronic structure of Tm^\mathrm\ensuremath- and a recent experimental investigation of Tm^\mathrm\ensuremath-.
