[en] Consideration is given to results of studying peculiarities of radiation defect accumulation for the case of monocrystal tungsten ion irradiation by nitrogen and neon at different ion current densities. Implantation was conducted at energies E=150 keV and two ion current densities - J=2 and 20 μA/cm in random-direction. It is shown that nitrogen atoms promote radiation defect accumulation and lead to involvement of intercascade processes in secondary defect formation with achievement of high N⁺ doses. 3 refs.; 1 fig

[en] The proceedings consist of four parts covering the following subjects: physics of orientational effects; electron and positron radiation in solids; some issues of ion implantation; beams use under materials composition and structure analysis

[en] Potentiality of using alpha-channeling for determination of boron atom disposition in silicon is considered. Results of experimental study of silicon crystal, doped with boron, are presented

[en] Consideration is given to results of applying new approach to description of dynamic chaos in channeling, based on the generalised method of optical potential (OP) in quantum channeling theory. The description of generalized OP in formalism leads to new quantum-mechanical peculiarities of dynamic chaos, which must be also observed in experiment and can be used for testing of theory predictions. The obtained results enable to perform experimental study of dynamic (quantum in particilar) chaos manifestations, taking the charged particle channeling as an example. 7 refs

[en] Possibility of measuring anomalous magnetic moment (AMM) of high energy electrons and positrons in crystals is shown. The dependence of depolarization degree of electrons and positrons AMM in the case of their transmission through tungsten crystal is presented. It is shown that for e^± with 100 GeV energy depolarization degree decreases twice in the case of amorphous substance. 4 refs.; 1 fig

[en] Possibility of using accelerator heavy ions for study of element distribution profile in near-the-surface layers is considered. It is proposed, that use of heavy ions when studying profiles by the method of recoil nucleus detection of analyzed element (ERD) is very promising, i.e. only Rutherford scattering can be taken into account up to energies, close to the barrier. It is shown that this technique is preferable for study of distribution profiles of heavier elements: C, N, O. Ar⁸⁺ ions, accelerated up to 58 MeV energy were used for this purpose. 2 refs.; 2 figs

[en] Transmission of channeled antiprotons to large depths ∼ 5 μm was investigated. Calculations were conducted for ∼ 4 MeV particles, passing through crystal, composed of chains. Potential of I/r type was used for motion simulation according to Monte-Carlo method. Multiple scattering was taken into account as addition to azimuthal and vectorial angle. Stopping power of antiprotons was calculated, assuming that particle energy losses consisted of energy losses of interaction with atomic core and energy losses on valent electrons. 3 refs.; 2 figs

[en] A study was made on peculiarities of accelerated P⁺ ion interaction with thin films of bis-2.6-(9-antrylstyryl)-4-dicyanmethylene-4H-pyran (C₄₀H₂₄N₂O). Irradiation of analyzed films by 40 keV phosphorus ions resultes to intensive change of substance composition in dose range of 10¹⁵... 10¹⁶ at/cm². Nitrogen concentration in surface layer decreases with growth of irradiation dose and is equal to 68 and 52% of initial film content for 4 x 10¹⁵ and 7 x 10¹⁵ at/cm² doses respectively. 2 refs.; 2 figs
