  Continuing with previous works, we present a cosmological model in which dark
matter and dark energy are modeled by scalar fields $\Phi $ and $\Psi$,
respectively, endowed with the scalar potentials $V(\Phi)=V_{o}[ \cosh
{(\lambda \sqrt{\kappa_{o}}\Phi)}-1] $ and $\tilde{V}(\Psi)=\tilde{V_{o}}[
\sinh {(\alpha \sqrt{\kappa_{o}}\Psi)}] ^{\beta}$. This model contains 95% of
scalar field. We obtain that the scalar dark matter mass is $m_{\Phi}\sim
10^{-26}eV.$ The solution obtained allows us to recover the success of the
standard CDM. The implications on the formation of structure are reviewed. We
obtain that the minimal cutoff radio for this model is $r_{c}\sim 1.2 kpc.$
