Differential ionization cross-section of hydrogen bromide

European Journal of Mass Spectrometry, 2022
In this study, the relative single and double differential ionization cross-section of the hydrogen bromide molecule and their fragmented ions (HBr + , Br + , H + ) have been theoretically evaluated. In the single

Calculation of the differential photoionization cross-section of formaldehyde

Chemical Physics Letters, 2001
Abstract The integral and the differential photoionization cross-sections of formaldehyde are computed in the random phase approximation (RPA) coupled with a K-matrix (KM) based technique. The molecular orbitals in the continuum are projected on suitable L2 special polynomial Gaussian functions.

Differential scattering cross-sections for CNA2Π+Ar

The Journal of Chemical Physics, 2007
We present the first results from a novel experimental approach to the measurement of state-to-state differential scattering cross-sections for inelastic scattering of electronically excited CNA2Π with Ar. Photodissociation of ICN with linearly polarized 266nm radiation generates CNX2Σ+ (υ″=0,J″) with a near mono-energetic speed distribution and large ...

The differential cross-section

1998
This chapter examines the differential cross-section, which characterizes the scattering angle dependence of the collision or reaction cross-section. It begins by looking at elastic scattering. Non-reactive collisions may be categorized into those which conserve kinetic energy (elastic collisions) and those which do not (inelastic collisions ...

Differential cross sections and polarization of in collisions

Journal of Physics B: Atomic, Molecular and Optical Physics, 1998
The presence of an axially symmetric angular distribution of energetic protons in astrophysical plasmas can be detected by measuring the linear polarization of the lines emitted from collisionally excited levels of atoms. Another signature of proton beams can be found in the study of line profiles.

Deconvolution of experimental differential cross sections

The Journal of Chemical Physics, 1989
A method to deconvolute experimental differential cross sections is presented. The procedure removes the effect of the angular divergence of the primary beam, the finite size of the detector, and multiple scattering. The resulting cross section is the optimal experimental result.

Parametrization of multiply differential cross sections

Zeitschrift für Physik D Atoms, Molecules and Clusters, 1992
Multiply differential cross sections for two- and three-electron escape are parametrised in terms of generalised tensorial asymmetry parameters. The analysis is based exclusivly on rotational invariance as an exact symmetry for the experimental set up. No approximate assumptions are made on the correlated dynamics of many- electron systems. Results are

Differential cross section of multiphoton ionization

Journal of Physics B: Atomic and Molecular Physics, 1975
Differential cross sections for multiphoton ionization of atomic hydrogen are calculated for the range of two photons to eight photons. Some possible applications of such information are suggested.
