  "abstract": "Angle‐resolved photoelectron spectroscopy (ARPES) has been used to probe the electronic and vibrational structure of the Cu5− cluster. High‐resolution spectra recorded near the detachment threshold reveal well‐resolved vibrational progressions, enabling a precise determination of the adiabatic electron affinity (EA = 1.8947(12) eV). Measured vibrational frequencies are in good agreement with density‐functional‐theory predictions, allowing the assignment of the observed modes. The anisotropy parameter β of the photoelectron angular distribution from the highest occupied molecular orbital follows the universal momentum‐dependent behaviour recently predicted. In some cases β exhibits a dependence on the final vibrational excitation of the cluster which deviates from the prediction, revealing a possible influence of autoionizing excited states.",
