  A calculation of the classical analogue for the quantum wave function and
local denity of states, in energy representation, is presented for simple
Hamiltonian systems. Sucha analogous were proposed by M. V. Berry and A. voros
considering the intersection of energy shells of two systems as the only
semiclassical object which can give support to eigenfunctions. One of them is
the system unser study and the other is the "unperturbed system" used to
express the wave functions, even in the case that both systems are not close.
For simple systems and as for scalable ones analytical expressions are
obtainable. In the present work we offer examples of both.
