Observation of anisotropic interactions and molecular orbitals of CO upon collision with He*(23S) atoms by two-dimensional Penning ionization electron spectroscopy
نویسندگان
چکیده
By collision-energy/electron-energy-resolved 2D Penning ionization electron spectroscopy as well as by theoretical calculations of the collisional ionization dynamics, the outer shape of molecular orbitals for ionization to X(Σ) and A(Π) states of CO was sensitively probed, and the anisotropy of the interaction between He*(2S) and CO was determined. Ionization to the B(Σ) state of CO was assigned to autoionization from superexcited states by angle-resolved electron spectroscopy and theoretical simulations.

Two-dimensional Penning Ionization Electron Spectroscopy of CH3I and CH2I2 by He*(2S) Metastable Atoms
Penning ionization of iodomethane (CH3I) and diiodomethane (CH2I2) upon collision with metastable He(2S) atoms was studied by collision-energy/electron-energy resolved two-dimensional Penning ionization electron spectroscopy (2D-PIES) over a wide range of collision energies (20 – 350 meV). Collision energy dependence of partial ionization cross sections (CEDPICS) indicates that the interaction ...

Surface Penning ionization (SPI) in the process He*(2lS, 23S) + CO + He(llS) + CO+ + eis investigated theoretically for CO molecules chemisorbed on a Pd(ll1) surface at low collision energy of metastable He*-beams. The actual process can well be explained in terms of Auger deexcitation. The entire SPI process occurs at the topmost layer, thereby increasing the surface sensitivity. The potential...

Metastable He*(21S,23S) atomic beams at thermal energies have been used more frequently as soft surface probes recently. Due to the He*J< surface (M) interactions there is a certain probability I' of He being deexcited in front of the surface. The deexcitation energies (E* = 20.6 and 19.8 eV respectively for He * 1 -2 S and -23S) that are released are sufficient to ionize electrons of surfaces....

In the present work, the total cross-section for the ionization of H, He, Ne and Ar atoms by +He2+ ، H+ ، Li3 ions has been calculated. In these calculations, a binary encounter approximation in the form of a two-body process between projectile ions and atomic electrons at the high energy range has been implemented. In order to enter the nuclear role of the target atom, the atomic electron vel...

The ionization dynamics of pure He nanodroplets irradiated by Extreme ultraviolet radiation is studied using Velocity-Map Imaging PhotoElectron-PhotoIon COincidence spectroscopy. We present photoelectron energy spectra and angular distributions measured in coincidence with the most abundant ions He(+), He2(+), and He3(+). Surprisingly, below the autoionization threshold of He droplets, we find ...
