Homework Statement
this problem is from (chapter 2 problem 1, gasiorowicz, quantum physics) where I am given
A(k) = N/(k2+a2) and must calculate psi(x)
Homework Equations
I am using the equation
psi(x,t) = integral from - infinity to + infinity A(k) ei(kx-wt) dk
which when t=0 goes to
psi(x,t) = integral from - infinity to + infinity A(k) eikx dk
The Attempt at a Solution
integral from - infinity to + infinity of
N/(k2+a2) * eikx dk
is this a good approach? How can I solve the integral?
any help would be greatly appreciated
thank you
