Photo-Ionisation of Atomic Oxygen

Part of the Physics of Atoms and Molecules book series (PAMO)


The first calculation of the cross section for photo-ionisation of atomic oxygen was made by Bates, Buckingham, Massey and Unwin (1939) using a Hartree self-consistent field (scf) approximation, without exchange. The wave function Ψb for the initial bound state was taken to be the scf function for atomic oxygen calculated by Hartree and Black (1933) and the function for the final continuum state was
$$\mathop{\psi }_{c}=\psi \theta $$
with Ψ the scf function for 0+ and θ\(\theta \left( {\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{r}}\right)\) the wave-function for the ejected electron, calculated in.the field of 0+. A calculation similar to that of Bates et al. was made by Yamanouchi and Kotani (1940).
