“…In subsequent calculations, Sinanis et al [35] computed the resonance parameters systematically in the framework of state-specific configuration interaction in the continuum and obtained a theoretical value consistent with the above measurement. Very recently, Tsednee and Yeager [36] applied the complex-scaled multiconfigurational spin-tensor electron propagator (CMCSTEP) technique and obtained the B − shape resonance parameters as E r = 0.126 eV and τ = 0.061 eV, again in reasonable agreement with the experimental result [34]. The present calculations clearly show that the theoretical position of this resonance is extremely sensitive to the number of channels included in the close-coupling expansion.…”

We present a comprehensive study of electron collisions with boron atoms by using the B-spline R-matrix method for electron energies ranging from threshold to 100 eV. Elastic, excitation, and ionization cross sections were obtained for all transitions between the lowest 11 states of boron. A multiconfiguration Hartree-Fock method with nonorthogonal term-dependent orbitals was employed to generate accurate wave functions for the target states. Close-coupling expansions including 13, 51, and 999 physical and pseudo target states of boron were used to check the sensitivity of the results to changes in the theoretical model. The cross-section dataset obtained from the large-scale calculations is expected to be sufficiently accurate and comprehensive for most current modeling applications involving neutral boron.
