STATE DEPENDENCE OF NP(4) (2S-CORRELATION PATTERNS IN DOUBLE PHOTOIONIZATION(1)L ANGULAR)

Measurements of the neon 2p(4 3pe), D-1(e) and S-1(e) triple different ial cross section (TDCS) for photoionization under equal energy sharin g are presented. The experimental data are found to be well reproduced by a model in which the TDCS is parametrized in terms of the relative magnitudes and phases for the epsilon s epsilon p and epsilon p epsil on d continuum channels and an electron correlation factor. Within thi s model, the final-state continuum wavefunction is formulated with res pect to the contributing LS components, which allows an analysis of th e effects of their different symmetries upon angular correlation patte rns.
