Exercise 31 Wkb Currents In More General Context 10 Point Graded Consider The General Wkb Solution For An Allowed R 1 (40.43 KiB) Viewed 34 times

Exercise - 31: WKB currents in more general context 10 point (graded) Consider the general WKB solution for an allowed region: • (a) = A xp (iſ**(z) de') + Coxp(--**(de'). S + А √k (x) B -exp √k(a) where A and B are complex numbers. Calculate the probability current density J (*) for this wavefunction Since the current is a non-linear function of the wavefunction it is not clear if the current J (s) is the sum of the currents that would arise from each term in the wavefunction. Write your answer in terms of A, B.h and m. Note that A and B are complex numbers, and so functions like abs() and cons may be used.
