I have found an expression for the estimated energy contribution a term |I> will bring to a wavefunction |K>
[itex]\Delta E = \frac{|\langle I|\hat{H}| K\rangle|^2}{(E_K - \langle I |\hat{H}| I\rangle)}[/itex]
Is there a simple way to extract the coefficient that will be associated with |I>? Even a link to relevant literature would be appreciated.
Thanks
