For the half-harmonic oscillator (Example 9.3), make a plot comparing the normalized WKB wave function for n
Question:
For the “half-harmonic oscillator” (Example 9.3), make a plot comparing the normalized WKB wave function for n = 3 to the exact solution. You’ll have to experiment to determine how wide to make the patching region.

Example 9.3 Potential well with one vertical wall. Imagine a potential well that has one vertical side (at x = 0)) and one sloping side (Figure 9.11). In this case (0) = 0, so Equation 9.47 says 1/16 20 or S² ["podx = (x - 1) xh. p(x) For instance, consider the "half-harmonic oscillator", л p(x)dx + = nπ, (n = 1, 2, 3, ...). 4 V(x) = In this case where x2 = p(x)=√√2m [E- (1/2)mw²x²] = mw√√ mw²x², (x > 0), En 2E (otherwise). 1 w m is the turning point. So #x2 ΠΕ S • 105 - p(x)dx = mw √√√x²-x²dx = ==mwx² = 20 and the quantization condition (Equation 2.48) yields = ( 2₁ - ²2 ) Fio = (2²/₁ 3 7 11 2' 2' 2 **** ħw.
