Heavy quark $c\overline{c}$ has been studied in the non relativistic framework using a quark-quark potential as a sum of power of the corresponding distance. The form of potential is based on phenomenological facts. The problem was solved numerically using a program written on C++. Mass spectra and the expectation value of the radius have been estimated for different quantum-mechanical states for $c\overline{c}$ system. The results have been compared with other similar and recent works. The mass spectra obtained is in acceptable agreement with the experimental data for $c\overline{c}$.

Palabras clave : charmonium; potentials; mass spectra; computer codes; schroedinger equation.
