Resumen:
We study numerically the decay of a Hamiltonian system whose transient
bounded dynamics is fully chaotic but not necessarily fully hyperbolic
when the phase space is initially populated by scattering experiments.
We show that parabolic subsets included in the trapped orbits set are
related to an algebraic tail corresponding to long times. The
characteristic exponent of such a tail and that corresponding to the
tail of the decay from the equilibrium population differ by one. This
fact, already observed in other non-hyperbolic systems, is related to
internal distributions that characterize the internal dynamics of the
system.
