Poschl-Teller potential

    1. The problem statement, all variables and given/known data

    3. The attempt at a solution

    Because there is no wavefunction specified, is it sufficient to show A+A- = (ε+1) and hence perform the expansion [(-d/dx)+tanh(x)][(d/dx)+tanh(x)]?

    You should solve the differential equation, you'll see that \Phi goes as Exp[-ikx](tanh x + ik) + Exp[i k x] (tanh x - ik )
