5.7.1 So­lu­tion symways-a

Ques­tion:

How many sin­gle-par­ti­cle states would a ba­sic Hartree-Fock ap­prox­i­ma­tion use to com­pute the elec­tron struc­ture of an ar­senic atom? How many Slater de­ter­mi­nants would that in­volve?

An­swer:

Hartree-Fock would use 33 sin­gle-par­ti­cle states, com­bin­ing into a sin­gle Slater de­ter­mi­nant.
