Aa. Wills et al., IMPORTANCE OF SPIN-ORBIT EFFECTS IN PARITY-UNFAVORED PHOTOIONIZATION OF NEON, OBSERVED USING A 2-DIMENSIONAL PHOTOELECTRON IMAGING TECHNIQUE, Physical review letters, 80(23), 1998, pp. 5085-5088
We present an experimental and theoretical study of photoexcitation an
d decay mechanisms of doubly excited resonances in neon. New spin-orbi
t induced effects are identified in the angle-resolved and photoelectr
on-resolved differential cross sections for a parity-unfavored transit
ion. These observations are facilitated using a two-dimensional imagin
g technique, and highlight the importance of considering spin-orbit in
duced effects when studying detailed spectra in atomic systems as ligh
t as neon.
