Universal Scaling of Resonances in Vector Correlation Photoionization Parameters

“…Only for the particular case of a single final ion state, it was predicted for the anisotropy parameter β and the spin polarization of photoelectrons in [22].…”

“…Equations (12) and (13) have been presented in an equivalent form in [22,23]. They provide us with a new method of determining the Fano parameters q and ρ 2 by studying the scaling factors χ and the energy shifts .…”

“…For nearly symmetric Lorentzian-like resonances (|q| 1) the ratio / and the scaling factor χ can be much larger. For example, calculations [22] predict 120 meV (χ 100) for the Na 2p 5 3s 2 2 P 1/2,3/2 autoionizing states with q ∼ 300. The 'switch over' was also predicted for the resonances in the angular anisotropy parameters of the fluorescence after dielectronic recombination into the excited states of He [23].…”

“…To our knowledge, this effect has not been pointed out before. Particular cases of the above regularity have been discussed in [22,23] for the angular anisotropy and polarization of photoelectrons and for the angular distribution of fluorescence in the dielectronic recombination.…”

Resonances in angular distribution of secondary photons from an excited atom in the (e +A +) recombination

“…The "broadening" and "shift" phenomena for resonances in the coefficients of angular anisotropy for photoelectrons have been studied earlier in [23]. Formulae for ff and shift A suitable also for our case of recombination are of the form = rill + ~k(I + q~)/(t + o#) (30)…”
