Description

A comparative analysis of experimental and theoretical results for the near-threshold electron impact excitation of the np5(n+1)s22P3/2 autoionizing states in Na (n = 2), K (n = 3) and Cs (n = 5) is presented. The apparent simplification (from Na to Cs) of the observed resonance structure in the excitation functions actually conceals a significant complication of the collision process through increasing configuration-mixing and relativistic effects.
