Abstract
At first we solve the Schrödinger equation for a simple but, nevertheless, very important case. We consider electrons which propagate freely, i.e., in a potential-free space in the positive x-direction. In other words, it is assumed that no “wall,” i.e., no potential barrier (V), restricts the propagation of the electron wave.

Differential equation of a damped vibration for spatial periodicity (see Appendix 1)
$$ \frac{{{d^2}u}}{{d{x^2}}} + D\frac{{du}}{{dx}} + Cu = 0. $$(4.52)Solution:
$$ u = {e^{ - (D/2)x}}(A{e^{i\delta x}} + B{e^{ - i\delta x}}), $$(4.53)where
$$ \delta = \sqrt {{C - \frac{{{D^2}}}{4}.}} $$(4.54) - 5.
