SCHROD


APPARATUS
pc with "Schrod" program 105-12


DESCRIPTION
This program numerically solves the Schrodinger equation for a bound particle.  You specify the potential well, the energy level and the parity; and the program integrates the equation and graphs the potential function, the wave function, and the energy level.

You have eight choices for the potential well:
  • Simple harmonic oscillator  (V(x) = x*x/2)
  • Infinite square well, half width 1
  • Finite square well, half width 1 (you specify the depth)
  • "Linear potential"  (V(x) = |x|)
  • Ammonia atom model (V(x) = k*(|x|-A)*(|x|-A)/2 --you specify k and A)
  • Infinite square well, half width 1, with square perturbation--you choose the half width and the height/depth of perturbation
  • hydrogen atom--Coulomb potential with "centrifugal" term--you choose l (0, 1, or 2)
  • specify any potential in Pascal function format

  • After you have chosen a potential, you then enter an energy level and the parity; these set the initial conditions for the integration.  After the integration is completed and the graph is done you can enter another energy or parity, or choose another potential.
