  The short and intermediate range order of an amorphous GeSe$_4$ alloy
produced by Mechanical Alloying were studied by Reverse Monte Carlo simulations
of its x-ray total structure factor and Raman scattering. The simulations were
used to compute the $G^{\text{RMC}}_{\text{Ge-Ge}}(r)$,
$G^{\text{RMC}}_{\text{Ge-Se}}(r)$ and $G^{\text{RMC}}_{\text{Se-Se}}(r)$
partial distribution functions and the ${\cal
S}^{\text{RMC}}_{\text{Ge-Ge}}(K)$, ${\cal S}^{\text{RMC}}_{\text{Ge-Se}}(K)$
and ${\cal S}^{\text{RMC}}_{\text{Se-Se}}(K)$ partial structure factors. We
calculated the coordination numbers and interatomic distances for the first and
second neighbors and the bond-angle distribution functions
$\Theta_{ijl}(\cos\theta)$. The data obtained indicate that the structure of
the alloy has important differences when compared to alloys prepared by other
techniques. There are a high number of Se-Se pairs in the first shell, and some
of the tetrahedral units formed seemed to be connected by Se-Se bridges.
