The temperature dependence of the specific heat present for dimension D=3 a logarithmic dependence which shows that the fermionic excitations reaches a non - Fermi behavior. The result is in good agreement with the experimental data obtained recently for $Ni_x Pd_{1-x}$ alloys.14 pagesCondensed Mattertext
