[en] The method of multicontinuations is suggested to solve the problems of obtaining nonperturbative results using perturbation theory. The property of strong regularity (c-regularity) of perturbations is introduced. Some classical theorems are shown to be stable for relatively restricted perturbations and valid for the property of perturbation insignificant amount is substituted by the c-regularity property. Interrelation between c-regularity and holomorphy of operator and form families is considered

[en] A fission channel, based on thermodynamical fission model, has been added to the intranuclear-cascade-evaporation ITEP program. The calculated mass spectra and fission cross sections of ²⁰⁸U and ²⁰⁹Bi by neutrons and protons are in reasonable agreement with experimental data

[en] The spectrum of target radiation is estimated using statistical simulation of internuclear cascades of particles. It is shown that in case of target being of interest to generate intensively neutrons under the action of intermediate energy protons value E_eff and σ_f,eff don't practically depend on target material and they change weakly at beam energy. 11 refs.; 2 figs

[en] The following problems are considered in detail within the frames of the model of intranuclear cascade (MIC): number of interactions which a particle suffers in a nucleus (furthe on - multiplicty); different multiplicities contributing to particle production in kinematically forbidden region for particle scattering on a free nucleon; dependence of characteristics of interaction multiplicity on atomic weight of nucleus-target. pA reactions, where A is C or Pb nucleus, at kinetic energy of an incident proton T₀=8 GeV are considered. The conducted analysis confirmed expected qualitative characteristics of rescattering. Angular and energy distributions of interaction multiplicities can be explained wthin the frames of the model. Existence of high multiplicities both for a heavy Pb and light C nucleus turned to be unusual

[en] The process of proton production in pA-interaction into the back hemisphere in the frames of the intranuclear cascade model is considered. Good agreement of the calculated energy and angular spectra with the experimental ones is revealed. Analysis of the mechanisms of multiple rescattering of the particle on nuclear nucleons and absorption of π-meson on a two-nucleon flucton is conducted. Kinematic boundaries of manifestation of the investigated mechanisms are determined

[en] A new version of the program of statistical simulation of hadron-nucleus and light nucleus-nucleus interaction is elaborated. The cascade part of the program is described. The comparison of model predictions with the proton-nucleus interaction experiments is performed. A satisfactory calculations-experiment agreement is obtained

[en] Yields of π⁺, p, d produced in the interactions of incident protons at 4.54; 4.75; 4.95 GeV/6 with Be, Al, Cu, Ta nuclei are investigated. Measurements were performed by time-of-flight spectrometer maked on tDe base of separated beam of ITEP proton synchrotron. Tables of inclusive differential cross sections of investigated reactions are presented. Yields of d, t produced by protons of 2.03 GeV/A were measured. A special attention is paid to investigation of yields of deuterons with extremely large momenta (the region of direct reactions pp → dπ⁺, pd → dp)

[en] The new ITEP version of cascade-evaporation-fission code for simulation of hadron-nucleus interactions is discussed. Also some calculation results of neutron-nucleus interactions are presented. These data are intended for analytical approximation construction. 9 refs.; 5 figs

[en] In this paper we present experimental results on electron-exploded current opening switch powering from fast helical magneto-cumulative generator (MCG). Energy capacity of such MCG is about ∼1 kJ, total operating time is 25 μs, characteristic current rise time (in e-times) is ∼2.5 μs. Thin copper wires are used. Voltage pulses up to 200 kV with front ∼50 ns on resistive load of 25 Ohm, were formed at the experiments
