✦ Synopsis

Ireland (see application form in this Nature ofphysical problem issue) This set of subroutines can serve as a basis for Monte Carlo programs simulating electron-photon cascades. Computer: EC 1020, EC 10 series, IBM 360/, IBM 370; Installation: INRNE, Sofia Method ofsolution Every subroutine uses Monte Carlo techniques to simulate Operating system: EC Disk Operating System one of the following processes: bremsstrahlung, pair production, Compton effect, multiple Coulomb scattering. The sub-Programming language used: FORTRAN IV routine DIST calculates the ftee path realized in the interaction. High speed storage required: 3437 words Restrictions on the complexity of the problem No. of bits in a word: 32 The subroutines are designed for energies corresponding to screening parameter ~y< 2. Versions ofbremsstrahlung and Overlay structure: none pair productionprograms for full screening are also included. This means that the energy range is from several MeV to 1011 No. of magnetic tapes required: none MeV for air. In heavier media the energy interval is narrower because of the lack ofvalidity of the Born approximation Other peripherals used: none around the lower limit and the influence of the Landau-Pomerantchuk effect for the upper one. No. of cards in combined program and test deck: 730
