For a long time, the Bs0-[`(Bs0)] system has eluded a complete investigation of its
observables. Only recently, the Tevatron experiments have accumulated sizable Bs0
samples which allow a direct and precise study of the system properties. This
contribution reviews the most up-to-date measurements by the CDF and DØ Collaborations
of the Bs0-[`(Bs0)] system parameters: the mass and decay-width
differences, Dms and DGs between the heavy and light Bs0 mass
eigenstates, the average decay width Gs
and the CP -violating phase in the mixing fs.
