Abstract:

Inelastic electron scattering from the vibrations of N2, CO, O2 and H2 adsorbed in mono- and multiple layers on Ag films at T approximately 20 K show energy-dependent cross sections characteristic of resonance scattering via temporary negative ion states. The resonances for these adsorbed phases generally occur at lower energies than in the gas phase and have spectral features which indicate negative ion lifetimes of less than 10 the minus 14th power seconds.
