The ς+ hyperons are produced by the collisions of Λ hyperons from J/ψ decays with nuclei in the material of the BESIII detector. The total cross section of Λ+Be9→ς++X is measured to be σ=(37.3±4.7±3.5) mb with Λ momenta within [1.057,1.091] GeV/c, where the uncertainties are statistical and systematic, respectively.
