[SIESTA-L] error when generate the O2- Pseudopotential

2010-04-25 Por tôpico Fen Hong
Dear all I want to get the O2- Pseudopotential, valence orbital is 2s2 2p6. There still has error in the output while it worked when I tried the 2s2 2p5 3d1. Does anybody know the reason? the input is pg Oxygen tm2 2.0 n=O c=pb 0.0 0.0 0.0 0.0 0.0

Dear Andrei, So how do I calculate the total energy of a single atom with Siesta?I should use the same pseudopotential as what I use for the molecule, right?But for a single atom,do I place that atom at the origin? Thank you very much. Best regards, Haoliang Chen 在2010-04-25 14:30:07,apost...
