  In this work, a scattering process of quantum particles through a potential
barrier is considered. The statistical complexity and the Fisher-Shannon
information are calculated for this problem. The behaviour of these
entropy-information measures as a function of the energy of the incident
particles is compared with the behaviour of a physical magnitude, the
reflection coefficient in the barrier. We find that these statistical
magnitudes present their minimum values in the same situations in which the
reflection coefficient is null. These are the situations where the total
transmission through the barrier is achieved, {\it the transparency points}, a
typical phenomenon due to the quantum nature of the system.
