Problem 2. We are observing a particle with mass m and energy E in one of the two one-dimensional potentials below: V. for 0 < x < 2:a Vy(x) = { 0 otherwise otherwise or | Vo for 0 < x < a and 2 a < x < 3:a V2(x) = { á»Ÿ otherwise Both where () < E< V.. 2.1 Use the WKB-approximation to determine the tunneling probability T, through V.. Determine T, in each of the limits a>0, E-V, and â€ â€” and comment on the results. 2.2 We are now observing the potential V,. Sketch the real part of the wavefunction in the interval - a < x < 4â€¢a. Determine the tunneling probabolity T, through V, using WKB approximation and compare the results from T, and T2.
