So the wave function is:

Left-most region: Ae^(ikx) + Be^(-ikx)

Inside the well: Csin(lx) + D(cos(lx))

Right-most region: 0

where k and l are known.

The problem is with boundary conditions: On the left, we have both (continuity and continuity of derivative), but on the right we only have one (continuity). So we have 3 equations to solve for 4 variables... what gives?

If the context helps, I'm trying to figure out the probability that particles entering from the left in region 1 will be reflected back (i.e., the ratio of the probability flux in region 1 traveling to the left to the incident flux in region 1 traveling to the right).

Any help would be greatly appreciated.

Thanks,

Thomas.
