CCL: Implementing caculation of SAB overlap of two Kohn-Sham determinants



 Sent to CCL by: "Limor shenar Jackson" [limorsj ~ gmail.com]
 Hello,
 I would like to implement SAB=<psiA|psiB>which is the overlap of two
 Kohn-Sham determinants of
 two diabatic states. Can anybody help me with this calculation? For case of SAA
 and SBB it is required
 to get the value 1.
 Thank you!
