Homework Equations
Equation 1.20
$$ \int_{-\infty}^{\infty} \mid\Psi (x,t)\mid^{2} dx = 1 $$
Equation 2.5
$$ - \frac {\hbar^{2}}{2m} \frac {d^{2} \psi}{dx^{2}} + V \psi = E \psi $$
The Attempt at a Solution
(a)
$$ \Psi (x,t) = \psi e^{-i(E_{0} + i \Gamma)t / \hbar} $$
$$ \mid\Psi (x,t)\mid^{2} = \Psi^{*} \Psi = \mid \psi \mid^{2} e^{2 \Gamma t/ \hbar} $$
Using equation 1.20
$$ e^{2 \Gamma t/ \hbar} \int_{-\infty}^{\infty} \mid \psi \mid^{2} dx = 1 $$
This equality only holds true for all time if ##\Gamma## is zero.
(b) & (c) I am having a hard time understanding what to do, but (c) looks a little easier (probably since it's a shorter question) so I will try it first
Using equation 2.5, it seems they want me to plug in
$$- \frac {\hbar^{2}}{2m} \frac {d^{2} \psi(-x)}{dx^{2}} + V \psi(-x) = E \psi(-x) $$
But now what??
