Due Wed, Apr 26

(last hw, heck yeah!)

Required reading for this week: F+T Chapter 11.1, 11.2 (+11.3 for your cultural edification.) (Optional: Beiser through 6.7)

SHOW HINTS

1. F+T 5-4

(Hint available)

2. F+T 5-6a

3. F+T 5-7a

4. F+T 5-8

5a) Verify that for the case l=1, m=1, the spherical harmonic function (given in F+T table 11-2) is properly normalized.

b) Suppose that a bound-state energy eigenfunction has the form

where is a normalized spherical harmonic. What is the normalization condition on R(r)? Why?

(Hint available)

c) From F+T table 11-2, the spherical harmonic function for l=2, m=0 is .

Since m=0,. what can you say about the form of ?

Show that indeed satisfies the differential equation for ,

(with l=2, m=0.)
