Et. Kennedy et al., HIGH-RESOLUTION MEASUREMENTS OF PARTIAL PHOTOIONIZATION CROSS-SECTIONS IN HOLLOW LITHIUM - A CRITICAL COMPARISON WITH ADVANCED MANY-BODY CALCULATIONS, Physical review letters, 76(21), 1996, pp. 3915-3918
Photoelectron data for hollow lithium states obtained with unprecedent
ed high spectral resolution and sensitivity are presented. A critical
comparison is made with the most recent theoretical results. Partial c
ross sections are measured providing the first definitive test of adva
nced ab initio calculations for this highly excited four-body atomic s
ystem.
