摘要：

Photon-stimulated desorption of H- ions has been observed from a BaO surface for photon energies in the range of 3-5 eV, with a yield that increases sharply for energies above the threshold at 3 eV. A possible explanation is that a chemisorbed H atom captures a photoemitted electron and desorbs as H- via the Menzel-Gomer-Redhead mechanism.
