From an analysis of the flavor-tagged decay B{sub s}{sup 0}{yields}J/{psi}{phi} we obtain the width difference between the B{sub s}{sup 0} light and heavy mass eigenstates, {delta}{gamma}{sub s}=0.19{+-}0.07(stat){sub -0.01}{sup +0.02}(syst) ps{sup -1}, and the CP-violating phase, {phi}{sub s}=-0.57{sub -0.30}{sup +0.24}(stat){sub -0.02}{sup +0.08}(syst). The allowed 90% CL intervals of {delta}{gamma}{sub s} and {phi}{sub s} are 0.06<{delta}{gamma}{sub s}<0.30 ps{sup -1} and -1.20<{phi}{sub s}<0.06, respectively. The data sample corresponds to an integrated luminosity of 2.8 fb{sup -1} accumulated with the D0 detector at the Fermilab Tevatron collider.
