(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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)

2. Relevant 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

3. 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
