摘要: The R-matrix method is used to study electron collisions with the BeH+ molecular ion. diatomic version of UK Molecular codes and a configuration-interaction calculation first performed for target obtain its potential energy curves 19 lowest singlet triplet states. Scattering calculations are then done yield excitation rotational cross sections in range 0 − 14 eV. Additionally we also bound states BeH their quantum defects at equilibrium bond length 2.5369a0. Resonance positions widths Feshbach resonances e-BeH+ system obtained presented
