<p style="margin-top:0; margin-bottom:0">Hello all,</p>
<p style="margin-top:0; margin-bottom:0"><br>

<p style="margin-top:0; margin-bottom:0">For the Potassium pseudopotential <a class="element_anchor" target="_blank" href="http://www.quantum-espresso.org/wp-content/uploads/upf_files/K.pbe-mt_fhi.UPF" style="margin:0px; padding:0px; color:rgb(175,16,29); font-family:Arial,Helvetica,sans-serif; font-size:13px">K.pbe-mt_fhi.UPF</a> from
the website, I am trying to find the cutoff radius.</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">When reading through the file, I see that in the Nonlocal section, cutoff radii are provided for each of the angular momenta (except for the s-orbitals), but what units are these in? Also, I noticed that the s-orbital
is not listed in either this section, nor in the semilocal section where the beta projectors for calculating the nonlocal component are listed (no L=0).</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">Why might the L=0 projector not be detailed within the file? And is it safe to assume that for all L the cutoff radius applied would be the same?</p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">I would very much appreciate any clarification on this matter.</p>
