We present a measurement of the relative branching fraction, R_{f_{0}/phi}, of B_{s}^{0} to J//psi f_{0}(980), with f_{0}(980) to pi^+ pi^-, to the process B_{s}^{0} to J/psi phi, with phi to K^+K^-. The J/psi f_{0}(980) final state corresponds to a CP-odd eigenstate of B_{s}^{0} that could be of interest in future studies of CP violation. Using approximately 8fb^-1 of data recorded with the D0 detector at the Fermilab Tevatron Collider, we find R_{f_{0}/phi} = 0.275 +- 0.041(stat) +- 0.061(syst)
