Electron impact ionization of water molecules in ice and liquid phases

Electron inelastic mean free paths in Ti, TiC, TiN and TiO2: A Theoretical Approach

“…In this paper we have calculated electron inelastic mean free path (IMFP) as a function of energy for bulk forms of silicon Ti, TiC, TiN and TiO 2 by employing atomic/molecular inelastic cross sections derived by semi-empirical quantum mechanical method developed earlier [2]. A general agreement of the present results is found with the most available data [1].…”

Electron-induced chemistry of methyl chloride caged within amorphous solid water

“…Water dissociation cross-sections σ H 2 O at electron energy of 1-50 eV were assumed energy independent and thus identical to values reported in the literature for electrons at 100 eV and 200 eV. 54,[58][59][60][61] Experimentally the ratio product/parent molecules was ≈1:100. This 1% yield has led us to consider the recombination rate constant k rec H 2 O as larger by several orders of magnitude than the water dissociation cross section, leaving [H 2 O] practically a constant value.…”

Electron and Positron Impact Ionization Cross Sections of O and Hg Atoms

“…The ratio value 'R p ' is chosen to be 0.7, which though approximate, turns out to be a meaningful input. This particular choice has been discussed in literature [9][10][11]. The peak position E p of the cross section Q inel occurs at incident energy where the discrete-excitation sum is decreasing while Q ion is rising fast, suggesting the R p value to lie between 0.5 and 1.…”

“…The imaginary potential term referred to as the absorption potential and denoted by V abs was given by Staszewska et al [8]. Modification in the original V abs is discussed in [9][10][11]. The Schrödinger equation with the modified V abs is solved by the variable phase approach [12], in order to determine Q el , Q inel and Q T [13].…”

“…Although the ionization cross section is contained in the inelastic cross section, there seems to be no rigorous treatment to project out Q ion from Q inel . However, a meaningful theoretical procedure has been in vogue in literature of the last two decades [1][2][3][4][9][10][11]. The theoretical method CSP-ic starts with the following function of incident energy E i .…”
