Positive Energy Solutions to Dirac Potential
The general solution for E > 0 is:
(x) =

Continuity of (x) at x = 0 gives:
(0) = A + B = A+ + B+ .

Free Particles
Now consider a particle that occupies a region of space where V (x) is the same value
everywhere (say, V = 0) we call this a free particle. Time-independent Schr"odinger
equation with V (x) = 0 is

Warm-up Question
A spaceship has a force, F1, acting on it in the +x
direction. It also has two other forces, F2 and F3
acting 120o up and 120o down from the +x
direction, respectively. If the spaceship is
traveling at a co
