Chapter 5: The Wigner Representation
Wigner representation of a collision of a Gaussian wavepacket with an Eckart. barrier
The wavefunction,
associated with the middle movie corresponds to the wavefunction in the animations of Ch. 7

v0=75/5 , v1=20/5
Most of the wavepacket is reflected. Note the change in sign of the momentum
![(Animation) A.](ch5/wg_ref_tra_a1.gif)
v0=75/9 , v1=20/9
The wavepacket bifurcates with significant positions reflected and significant positions transmitted
![(Animation) B.](ch5/wg_ref_tra_a2.gif)
v0=75/22 , v1=20/22
Most of the wavepacket is transmitted. there is no change of sign in momentum
