5.7.2 So­lu­tion symways-b

Ques­tion:

If two more sin­gle-par­ti­cle states would be used to im­prove the ac­cu­racy for the ar­senic atom, (one more nor­mally does not help), how many Slater de­ter­mi­nants could be formed with those states?

An­swer:

The 34-th state would in­tro­duce 33 more Slater de­ter­mi­nants, and the 35-th an­other 561, for a to­tal of 595.
