## Photoexcitation-autoionisation rate coefficients

The basic process is $1{\rm s}^2 nl + \gamma \rightarrow 1{\rm s}nln^\prime l^\prime \rightarrow 1{\rm s}n^{\prime\prime} l^{\prime\prime} + {\rm e}$

A separate file is provided for each n , which contains data for all n'> n . Note however that $1{\rm s}nln^\prime l^\prime \leftrightarrow 1{\rm s} 2 n^\prime l^\prime + \gamma$

has to be considered consistently at the same time to avoid multiple counting. Separate files are given for term (LS) coupling and intermediate (IC) coupling.
