[Pw_forum] choosing oxygen and Hydrogen pseudopotentials

[Nicola Marzari]

Indeed - although it's difficult to get accurate results for this 
particular problem with most
xc functionals. A safe bet would be to start from PBE or revPBE or 
PBEsol; for
the pseudo the US RKKJ tend to have been tested quite extensively.
