摘要：

The B-spline R-matrix method is used to investigate electron scattering from neutral calcium and photodetachment of Ca- in the low-energy range from threshold to 4 eV. The multiconfiguration Hartree-Fock method with nonorthogonal orbital sets is employed for an accurate representation of the target wave functions. The close-coupling expansion includes 39 bound states of neutral calcium, covering all states from the ground state to 4s8s S-1. The present calculations yield good agreement with the few available experimental data for both elastic electron scattering and photodetachment of Ca-. The prominent resonance structure in the low-energy region is analyzed and discussed.
