The electron emission spectra resulting from thermal collisions of He ∗(2 3S) metastable atoms with a Si(111)-7 × 7 surface were measured. Upon the oxidation of the surface, the deexcitation process of the metastable atom is found to change from resonance ionization followed by Auger ...

The observed spectral change in metastable-atom electron spectrum indicates that the surface reaction can be realized by the selective ionization of the outermost surface with the impact of slow metastable atoms. 展开 关键词: surface reaction MAES Penning ionization electron spectroscopy titanyl ...
Penning ionization of propionitrile (CH3CH2C⋮N), acrylonitrile (CH2CHC⋮N), and 3-butenenitrile (CH2CHCH2C⋮N) upon collision with He*(23S) metastable atoms has been studied by two-dimensional Penning ionization electron spectroscopy in which Penning electron intensity is measured as a fun...

Excitation of the $3^{1,3}D$ and $4^{1,3}F$ levels of helium by electron impact has been studied by time-resolved spectroscopy of the $3^{1}D$rightarrow${}2^{1}P($lambda${}6678AA{})$ and $3^{3}D$rightarrow${}2^{3}P($lambda${}5876AA{})$ t... RJ Anderson,RH Hu...
All-atom molecular dynamics (MD) simulations of bC88-DNAa and bC810-DNAa further supported the existence of a curled conformation and indicated an enhanced prevalence at high temperatures. Folding stability was characterized by calculating the relative solvent-accessible surface area (SASA) of the ...
