Winter Quarter 2007
Dr. Herbst
HOMEWORK ASSIGNMENT # 2
DUE: WEDNESDAY, 31 JANUARY
1. Bernath, page 153, Problem 10
2. Bernath, page 153, Problem 11
3. Use the simple independent electron model without electronelectron repulsion to
calculate the three ionization potentials of lithium. Compare your results with
experimental values. Can you think of a more appropriate independentelectron
approximation? Hint: consider the possibility of electrons screening the nucleus from
other electrons.
4. Bernath, page 153, Problem 8
5. Enumerate the RussellSaunders term symbols for the terms (“multiplets”) arising
from the configurations np
4
and nd
2
. Order these according to increasing energy.
Explain why the terms for np
4
are the same as those for np
2
. Then enumerate the possible
J values for the p
4
terms, label the states, and calculate the spinorbit splittings in terms of
A.
6. Determine and order the terms arising from the first excited configuration of nitrogen.
