【 摘 要 】

Electron capture cross sections in collisions of protons with the nitrogen molecule are obtained with two semiclassical ab initio methods: one uses multireference configuration interaction wavefunctions while the other is based on monoelectronic wavefunctions and the independent particle approximation. The accuracy and usefulness of this last, simplified, approach is discussed in view of its applicability to study larger systems.
