The sensitivity of measurement of Λ - Λ̅ oscillation in the external field at BES-III experiment is considered. These considerations indicate an alternative way to probe the Δ B =2 amplitude in addition to neutron oscillation experiments. Both coherent and time-dependent information can be used to extract Λ -Λ̅ oscillation parameter. With one year's luminosity at BES-III, we can set an upper limit of δ m < 10^-15 MeV at 90 to about 10^-6 s of - oscillation time.
