Here we take a direct approach to calculating reflection probability for tunneling, meanwhile obtaining a relationship applied in other exercises.

(a)Write out the smoothness conditions at the boundaries between, regions for the E0 barrier. From them, show that the coefficient B of the reflected wave is given by

(b) Verify that the reflection probability R given in equation (6-16) follows from this result.
