    • The pseudo-orbital is not normalized by construction [Eq. (17)]; however, this does not affect the resulting effective potential as the pseudo-orbital could be multiplied by any number and the effective potential would be unchanged [Eq. (20)]. The effect of an unnormalized PK pseudoorbital is to slightly increase the amount of pseudocharge density in the core region relative to outside the core. So-called norm-conserving pseudopotentials (Ref. 30) correct for this behavior; however, they are not based on the rigorously derivable PK theory.
