3. Suppose a beam of particles of mass m and kinetic energy E is incident from the left on a potential well given by:
U(x) = ?U0 (for 0 < x < L where U0 > 0)
U(x) = 0 ( otherwise )
(a) What is the Schrodinger Wave Equation (S.W.E.) for the region x < 0 ? (Hint: include both incident and reflected waves)
(b) What is the S.W.E. for the region x > L ? (Hint: this will only be a transmitted wave)
(c) What is the S.W.E. for the region 0 < x < L ? (Hint: in general there are two terms)
(d) What are the four boundary value equations for this case?
(e) Starting from the boundary value equations, derive the Transmission Probability (T) for this case.
