Schrodinger's equation and potential energy

  1. Mar 24, 2007 #1
    1. The problem statement, all variables and given/known data

    1. In a region of space, a particle with zero total energy E has a wavefunction

    ψ (x) = A x exp - (x2/L2)

    a) Find the potential energy U as a function of x
    b) Make a sketch of U(x) versus x

    2. Relevant equations

    time independent schrodinger's equation

    3. The attempt at a solution


    judging by the nature of the equation, the graph of U(x) against x seems to be that of a quadratic curve with the minimum point below the y-axis.

    did i get it correct? im abit uncertain...
