Lambda-Baryon Production in pi(+-)n Interactions
  The process of Lambda-baryon production in pi-p collisions is considered. The contribution of the string-junction mechanism to the strange baryon production in meson-baryon scattering is anlysed. The results of numerical calculations in the framework of the Quark-Gluon String model are in reasonable agreement with the data.
