Abstract
The hypervirial theorem was first introduced for bound-state systems and, subsequently, extended to one-electron scattering problems. In this paper electron-atom collisions are considered and the appropriate form of the hypervirial theorem is derived. Its relation to the original formulation is discussed. Application is made to the electron-hydrogen problem. Both elastic and inelastic collisions are investigated.Keywords
