“…Ionization via the covalent channel was confirmed by a spin-polarized measurement. 31 ͑ii͒ The intensity ratio of the first two bands I(1)/I(5) is 0.38Ϯ0.05, which is in good agreement with the reported values, 0.38, 29 0.40, 3 and 0.43. 28 This ratio means that the Penning ionization rate for the 5 state is about 5 times higher than that for the 1 state, taking their orbital degeneracy into account.…”

“…The unique feature of MAES that provides selective information on the outermost surface layer is especially useful for the study of the electronic states of molecular adsorbates. In this section, we deal firstly with carbon monoxide adsorbed on metal surfaces, because this system is regarded as a prototype of molecular adsorption and also Penning ionizations of CO ,, and transition-metal carbonyls , are well studied in the gas-phase. After a brief review of the results of free CO and transition-metal carbonyls, we present and discuss the MAES of CO adsorbed surfaces, which include the deexcitation channel of incident metastable atoms, the relative intensity of CO-derived bands, and a structure observed near the Fermi level.…”

“…Over the past years numerous experimental [1][2][3][4][5][6][7][8][9][10][11][12][13][14] and theoretical [13][14][15][16][17][18][19][20] studies have addressed the dynamics of autoionizing collision complexes involving metastable helium atoms. In particular, rather detailed information exists for the basic processes He*(2 3S, 21S)+H/D [10,13,[18][19][20], which may be regarded as prototype systems for autoionizing collision complexes at thermal energies, while less effort was devoted to the investigation of heavier metastable noble gases [21][22][23][24][25].…”
