Scattering of electrons with formyl radical

Electron- and positron-driven molecular processes for H2O, CO2, and NH3 in their gas and ice phases

“…At energies much beyond the ionization threshold (I), the first term in eqn (8) eventually becomes less important than the second. 68 For the e + collision, the following inelastic channels are open: I. Excitation: e + + XY -XY * + e + II. Direct ionization: e + + XY -XY + + e À + e + III.…”

“…In the SCOP formalism, to obtain the Q inel , the complex optical potential ( V opt ) is employed in the Schrodinger equation, which is solved numerically using the partial wave analysis. 68 η l = exp[−2 Im δ l ( k )] is the inelasticity factor and δ l ( k ) are the complex phase shifts. The Q inel can be partitioned by the contributions.…”

Theoretical Investigation of Dissociative Electron Attachment of Acrylonitrile

“…The resonance positions and widths obtained here are used for the DEA cross-section calculations. More details about the R-matrix method are given in earlier publications, 21,22,28−30 and the methodology employed for DEA cross-section calculations 31,32 is explained in brief below and can also be found in the report by Munro et al 33 The DEA cross-section σ DEA (E) is determined by the algebraic product of the probability of stability of the transient negative ion (TNI) "S p " or in other words assuming that TNI will decay only through dissociative attachment and the initial attachment (resonance) cross-section "σ r (E i )" resulting due to capture of an electron by the target molecule to form the metastable intermediate negative ion resulting from an electron colliding with a target at the ground state. The TNI probability/stability is defined as the possibility of surviving against the nuclear relaxation beyond the crossing point (r c ) of the corresponding potential energy curves (PECs) of the neutral target and its anionic state (see Figure 1).…”

Theoretical Investigation of Electron Impact Scattering on Imidazole

“…Additionally, the resonance cross sections σ r are determined by calculating the resonance position and width using the RESON program and fitting the eigenphase sum to the Breit−Wigner profile, 25 as explained in our previous publication. 20…”
