   Abstract:
   We report the observation of two narrow resonances consistent with states of orbitally excited (L=1) Bs mesons using 1 fb-1 of $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV collected with the Collider Detector at Fermilab II detector at the Fermilab Tevatron. We use two-body decays into K- and B+ mesons reconstructed as B+-->J/psiK+, J/psi-->\mu^+\mu^- or B+-->[overline D]0pi+, [overline D]0-->K+pi-. We deduce the masses of the two states to be m(Bs1)=5829.4\pm 0.7 MeV/c2 and m(Bs2*)=5839.6\pm 0.7 MeV/c2.
