We present a measurement of the CP-violating parameter βsJ/ψ using approximately 6500 Bs0→J/ψ decays reconstructed with the CDF II detector in a sample of pp̄ collisions at √s=1.96TeV corresponding to 5.2fb -1 integrated luminosity produced by the Tevatron collider at Fermilab. We find the CP-violating phase to be within the range βsJ/ψ [0.02,0.52] [1.08,1.55] at 68% confidence level where the coverage property of the quoted interval is guaranteed using a frequentist statistical analysis. This result is in agreement with the standard model expectation at the level of about one Gaussian standard deviation. We consider the inclusion of a potential S-wave contribution to the Bs0→J/ψK +K - final state which is found to be negligible over the mass interval 1.009
