PHY251 Homework Set 8 Reading: Chapter 9 Homework: Chapter 9, Question 2, Problems 11,14,15,19; (extra credit: 23) Hints and Solutions Question IX.2 (10 points) In the quantum theory it is generally not possible to specify all three components of the angular momentum simultaneously. Is the l =0 angular momentum state an exception to this rule? Hints: No hints Solution: No Solution yet Problem IX.11 (15 points) Find r ² for the ground state of hydrogen. Compare your result with r ² for the same state. Hints: See example 9-6. Solution: No Solution yet Problem IX.14 (15 points) Show that in the state n =2, l =1, and m =0, r = 5 a 0 / Z . Set Z =1, and compare r with the result you found for the ground state of hydrogen in Problem 11. In doing your work, you will notice that the angular integrations are simple, because those parts of the wave functions have been normalized separately.
