“…The corresponding parameters calculated for the phosphorus atom in the local spin density approximation of the DFT and for the mercury atom calculated in the local density approximation are given, respectively, in works [10] and [25]. Note that, in the approaches of works [11][12][13][14][15], the potential components of the OP are determined by the electron density of a molecule.…”

“…Note that the approaches, in which spherical [13,14] and single-center [15] potentials are used, take absorption effects into consideration more consistently, as the absorption performed by the whole molecule, which is determined by the excitation of its spectra: electronic, vibrational, and rotational ones.…”

“…Basing on this approach, the methods of spherical [13,14] and single-center [15] molecular interaction potentials were developed. For instance, in works [13,14], the total wave function of a molecule and the corresponding electron density were determined in the framework of the Hartree-Fock method. At the same time, in work [15], the description used molecular parameters that were found by applying a much more complicated procedure, namely, a symmetryadapted, single-center expansion of the total multicenter wave function of electrons in a target molecule.…”

“…The cited authors applied the Schwinger multichannel method with pseudopotentials for the calculation of the cross-sections of elastic electron scattering by X 2 and XH 3 molecules (X = N, P, As, and Sb) at collision energies of 10, 15, 20, 25, and 30 eV in the static-exchange approximation. In this approximation, the electron interacts with the whole molecule, similarly to the methods used in works [12][13][14][15], but owing to the static and exchange potentials only. The introduction of a pseudopotential allows one to change a real potential arising due to the combined action of the nucleus and the core electrons in every atom of the molecule.…”

Potential Electron Scattering by P2 and P3 Phosphorus Molecules

Potential electron scattering by P2 and P3 phosphorus molecules at scattering energies of 0.5-30 eV has been studied theoretically for the first time. The research is carried out in the framework of the independent-atom model and using a real parameter-free relativistic optical potential for the electron interaction with atoms in the molecule. For the consistent description of the electron scattering by the atoms in the molecule, the potential parameters and the atomic characteristics are calculated in the local approximation of the stationary and time-dependent variants of the density functional theory. The comparison of the angular behavior of the differential cross-sections and the energy dependences of the integral ones in the cases of electron scattering by phosphorus molecules and phosphorus atoms testifies to their similarity.
