Dear all:<br><br>I download the NCPP pseuodopotential for Li from abinit website and use the fhi2upf.x tools to convert to UPF format. <br>the electron configuration of Li element is 1s2 2s2. So I input the parameter of '' label, occupancy" :<br>
<pre>------------------<br>Wavefunction # 1: label, occupancy > 2s 1<br>Wavefunction # 2: label, occupancy > 2p 0<br>Wavefunction # 3: label, occupancy > 3s 0<span style="font-size: 14px;"><br>Wavefunction # 4: label, occupancy > 3p 0</span><br>
<br>------------------<br></pre>I don't know whether the input is right? <br>But I feel something were wrong in the converted UPF file .<br><pre>------------------<br><span style="font-size: 14px;">nl pl l occupancy<br>
<br>2s 0 0 1<br><br>2p 0 1 0<br><br>3s 0 2 0<br><br>3p 0 3 0</span><br>------------------<br></pre>Why the l value of 3s and 3p state is 2 and 3 ? whether it is the result of the wrong input?<br>
According Paolo's advices that "the labels of l=0 to lmax valence orbitals (in the order:s,p,d,f,..)and a reasonable value for their occupancy" in previous Questions, the input is changed into:<br><pre>------------------<br>
</pre><span style="font-size: 14px;">Wavefunction # 1: label, occupancy > 2s 1<br>
Wavefunction # 2: label, occupancy > 2p 0<br>
Wavefunction # 3: label, occupancy > 2d 0<br>
Wavefunction # 4: label, occupancy > 2f 0</span><br>------------------<br><br>however the l value conflict with the n value in this case, the converted file seem to be right.<br><pre>------------------<br><span style="font-size: 14px;">nl pl l occupancy<br>
<br>2s 0 0 1<br><br>2p 0 1 0<br><br>2d 0 2 0<br><br>2f 0 3 0</span><br><br>-------------<br></pre>So I was confused by the case, which input is right and how to do with the "light atom" case?<br>
<br>Could someone tell me? <br>Thanks in advance!<br><br>Wang Di<br>
