We report the results of a study of the cumulative production of ..lambda.. hyperons in ..pi../sup -/C interactions at a ..pi../sup -/-meson momentum 40 GeV/c. The cross section for production of cumulative ..lambda.. hyperons is found to be sigma/sup ..lambda..//sub cum/ = 0.7 +- 0.2 mb. The fraction of ..lambda../sub cum/ is 5 +- 1% of all ..lambda.. hyperons in ..pi../sup -/C interactions at 40 GeV/c. Average values are given for the kinematic parameters of the ..lambda.. hyperons, together with the distribution of ..lambda.. hyperons in cumulative number and the dependence of the invariant cross sections on the kinetic energy and on the transverse momentum of the cumulative ..lambda.. hyperons. The results are compared with data of other studies at various primary-particle energies.
