Chapter 4, Problem 4.55P

(a)

To determine

Show that the radial wave function takes the form Rn(n1)=Nnrn1er/na, when l=n1 using the recursion formula and determine the normalization constant Nn by direct integration.

(b)

To determine

The expectation value of r and r2 for states of the form ψn(n1)m.

(c)

To determine

Show that the “uncertainty” in r(σr) is r/2n+1 for such states. Also sketch the radial wave functions for several values of n.
