[CP2K-user] Absorption spectra for bulk metals

[NGastaPooh]

Dear CP2K users,

I'm looking for a way to plot absorption spectra for bulk Na and K, so I 
can reproduce ARPES experimental data. I know that with some assumptions 
one can get band structures from ARPES data and directly compare them with 
calculated bands using DFT framework. However, I want to get initial 
intensity vs binding (initial state) energy spectrum. Is it possible to do 
so with CP2K? 

I would greatly appreciate any feedback.

Thanks,
Pooh
