Calculated cross sections for electron collisions with the BeN molecule

Abstract

We report a low energy electron collision calculation with the BeN molecule in its X 4Σ- ground state using the molecular R-matrix method at a single geometry, namely, the equilibrium Re = 3.045 a0 of the molecule. Using a suitable target model, we have calculated the elastic cross section and cross sections for electron impact excitation to several low lying excited states of BeN. Cross sections for electron impact dissociation is derived from the electronic excitation cross sections. In addition, molecular data on bound sates of BeN and e-BeN negative ion resonances and widths at the target equilibrium Re that may be relevant for other studies are also provided.

R-Matrix Calculation of Electron Collision with the BeO+ Molecular Ion

“…The inner-region solutions obtained were used to build an R-matrix at the boundary of the R-matrix sphere. For the outer-region solutions, it is more robust to propagate the R-matrix in the external region rather than the wave function itself (see, for example, [21]). The R-matrix was propagated in the outer region to an asymptotic distance R asy in a potential which, in addition to the Coulomb potential of the target, contained the dipole and quadrupole potentials of the target ion.…”
