Gamma-ray spectra of hexane (C6H14) in positron–electron annihilation process

Quantum chemical approach for positron annihilation spectra of atoms and molecules beyond plane-wave approximation.

TLDR
The present treatment succeeds in reproducing the Doppler shift, i.e., full width at half maximum (FWHM) of experimentally measured annihilation spectra for molecules with a mean absolute error less than 10%.

MOMENTUM DISTRIBUTIONS OF TWO PHOTON ANNIHILATING POSITRON–ELECTRON PAIRS IN HEXANE AND DECANE

Momentum distributions are calculated for electrons in the C–C and C–H bonds in hydrocarbons, using analytic SCF functions for atomic carbon orbitals and Heitler–London-type functions for the two

Angular distribution of two-photon positron annihilation in low energy positron scattering by the hydrogen molecular ion

Calculations are carried out to determine the angular distribution of gamma rays resulting from positron annihilation when low-energy positrons are scattered by the hydrogen molecular ion. Angular

Angular correlation of two-photon positron annihilation in molecular hydrogen and nitrogen

The calculation of the angular correlation of two-photon annihilation radiation for thermalized positrons colliding with simple molecules, particularly molecular hydrogen and nitrogen, is discussed

The fundamental nature and role of the electrostatic potential in atoms and molecules

Abstract. A variety of atomic and molecular properties can be expressed in terms of the electrostatic potential. These include energies, covalent and anionic radii, electronegativities (chemical

Electron momentum distributions in organic liquids

Positron annihilations have been investigated in a number of organic liquids, particularly hexane and benzene and their halogen derivatives. The angular distributions of the annihilation photons have

The anharmonic force field and equilibrium structure of methane

The anharmonic force field of methane has been refined to fit spectroscopic data from the isotopic species 12CH4, 13CH4, 12CH4, 12CH3D, 12CHD3 and 12CH2D2. Six of the thirteen cubic force constants
