what do you expect when you try to plot the density of states of a single hydrogen atom ?

a delta function at -1 Ry ?

Betreff: [Wien] DOS of isolated H atom

Dear WIEN2k community,

I am trying to plot DOS for isolated hydrogen atom in a large box
(20x20x20 a.u.), so the H atom is in the center of the cell (0.5; 0.5;
0.5 with P group of symmetry). I use Rmt(H)=0.7 a.u. and 1 k-point. But
when I try to plot the total H DOS or total DOS of the cell, I get zero
values. Does anybody have any idea what I did wrong? Is it possible to
plot DOS of isolated atoms in principle?

Thank you in advance.

Best regards,
