Abstract：
The phenomenological non-relativistic quark model has been employed to obtain the ground state masses of light vector mesons and their radially excited states and their decay widths. The full hamiltonian used in the investigation has kinetic energy, the confinement potential and the one-gluon-exchange potential. A good agreement is obtained with the experimental masses and their leptonic decay widths.
