A configuration-average distorted-wave method is developed to calculate electron-impact excitation and ionization cross sections for diatomic molecules and their ions. The method is based on the construction of bound and continuum orbitals on a two-dimensional numerical lattice in (r,{theta}) center-of-mass polar coordinates. Our first applications are the calculation of 1s{sigma}{yields}2p{sigma} and 1s{sigma}{yields}2p{pi} excitation cross sections and 1s{sigma}{yields}{epsilon}l{lambda} ionization cross sections for H{sub 2}{sup +}. Comparisons are made with plane-wave Born, distorted-wave, and R-matrix calculations, as well as experimental measurements.
