摘要：

The observed structure in the ionization cross section just above the threshold has been attributed to the formation of auto-ionizing Rydberg states. The calculation of the auto-ionization rates is discussed in terms of the breakdown of the Born-Oppenheimer approximation. Three aspects are examined qualitatively, the variation of decay rate with principal quantum number, the magnitude of the decay rate, and the competition between auto-ionization and pre-dissociation. It is found that the states are all narrow. and. that the widths decrease with increasing principal quantum number.
