[Pw_forum] best pseudo for Ni in b-NiOOH

2014-10-27 Thread francesca costanzo
Dear all, I am studying the b-NiOOH surface doped with Co. I was wondering which is the best electronic configuration to be used in the valence part of the UPS for Ni: 4s1d9 or 4s2d8? and in the case of Co: 4s1d8 or 4s2d7? Thank you in advance for your suggestions, Best regards,
