We discuss the possibility of searching for the \ensuremathΛ\ensuremath-\ensuremathΛ oscillations for coherent \ensuremathΛ\ensuremathΛ production in the J/\ensuremathψ\ensuremath→\ensuremathΛ\ensuremathΛ decay process. The sensitivity of measurement of \ensuremathΛ\ensuremath-\ensuremathΛ oscillation in the external field at BES-III experiment is considered. These considerations indicate an alternative way to probe the \ensuremathΔB=2 amplitude in addition to neutron oscillation experiments. Both coherent and time-dependent information can be used to extract the \ensuremathΛ\ensuremath-\ensuremathΛ oscillation parameter. With one year's luminosity at BES-III, we can set an upper limit of \ensuremathδm_\ensuremathΛ\ensuremathΛ<10^\ensuremath-15 MeV at 90% confidence level, corresponding to about 10^\ensuremath-6 s of \ensuremathΛ\ensuremath-\ensuremathΛ oscillation time.
