Abstract:
Reflection and transmission times through a linear potential is studied by using the stationary phase method. The incident particle is described by a wave packet constructed from a momentum distribution (k – k) highly concentrated around a fixed value k. The way the reflection and transmission times are calculated is similar to the way the phase time is defined for a rectangular potential.
