We combine the D0 measurement of the width difference between the light and heavy B{sub s}{sup 0} mass eigenstates and of the CP-violating mixing phase determined from the time-dependent angular distributions in the B{sub s}{sup 0}{yields}J/{psi}{phi} decays along with the charge asymmetry in semileptonic decays also measured with the D0 detector. With the additional constraint from the world average of the flavor-specific B{sub s}{sup 0} lifetime, we obtain {delta}{gamma}{sub s}{identical_to}({gamma}{sub L}-{gamma}{sub H})=0.13{+-}0.09 ps{sup -1} and |{phi}{sub s}|=0.70{sub -0.47}{sup +0.39} or {delta}{gamma}{sub s}=-0.13{+-}0.09 ps{sup -1} and |{phi}{sub s}|=2.44{sub -0.39}{sup +0.47}. The data sample corresponds to an integrated luminosity of 1.1 fb{sup -1} accumulated with the D0 detector at the Fermilab Tevatron Collider.
