 (1997)
 Oscillations of $\mbox{B}^0_{\mathrm s}$ mesons were studied in events with a large transverse momentum lepton selected from 3.2 million hadronic $\Zz$ decays registered by DELPHI between 1991 and 1994. A limit on the mass difference between the physical $\mbox{B}^0_{\mathrm s}$ states \Delta m_s 6.5 ~ \mbox{ps}^{-1}~\mbox{at 95\% C.L.} was obtained by combining the results obtained in three channels.
