The order parameter Omega defined by Landsberg, is calculated for nuclei an
d atomic clusters. The framework of information theory is employed. It is s
een that Omega is an increasing function of the number of particles N and t
he total kinetic energy T. The values of Omega are almost the same for the
two systems under consideration. It is conjectured that these properties ar
