[Pw_forum] Meatl USPP and light impurity atom

Dear all,

I've generated a metal USPP and the bands structure and DOS are very
similar to the ones calculated by an All Electron code. What is more,
both lattice parameter and Bulk Modulus are in excellent agreement
with experiments and the same happens to each and every calculation
that has been performed in which only the metal was involved.

However, awful results are shown when adding a light impurity atom,
namely H. For H, I've tried all PPs provided at QE's site.

Thanks in advance,
