K.Ph. Ustimenkov, I.D. Fedorets, I.I. Zalubovsky, N.S. Lutsaj

Abstract
Within the two-nucleon pion production mechanism the angular distrіbutions of cross sections and analyzing powers are calculated for the ground and two first excited levels of the residual nucleus in the ⁷Li(p,p^-)⁸B reaction at the proton energy Т_p = 200 MeV. With allowance for all first order diagrams a satisfactory correspondence between theory and experiment is obtained except for the level of the energy of 0.78 MeV in which case the one-nucleon mechanism witn the D⁺⁺ isobare excitation is to be included. The dominating shell model configurations formed in the studied reaction are found.

KEY WORDS: cross sections, analysing powers, two-nucleon mechanism, pion, r-meson, D-isobare.

ON THE POSSIBILITY OF DETERMINISTIC FOUNDATION OF QUANTUM MECHANICS

G.K. Khomyakov

Abstract
The possibility of creation of the unified deterministic scheme of classical and quantum mechanics, allowing to preserve their achievements, is discussed. It is shown that the canonical system of ordinary differential equations of Hamilton's classical mechanics can be added with the vector system of ordinary differential equations for the variable of quantization. This system appears to be directly linked with the tensor system of basic equations in terms of partial derivatives the affine invariant (trek) of which coincides with the stationary Schredinger equation. The selection of classical trajectories corresponding to the stationary states is being done according to the analog of Bohr-Sommerfeld rule. The case of non-relativistic particle without spin is considered.

KEY WORDS: basic equations, quantization, trajectories, stationary states.

EIKONAL SCATTERING OF RELATIVISTIC PARTICLESWITH ANOMALOUS MAGNETIC MOMENTIN EXTERNAL ELECTROSTATIC FIELD

N.V. Bondarenko, N.F. Shul'ga

Abstract
We consider scattering of relativistic particle, with account of its anomalous magnetic moment, in a finite range electric scattering field. The consideration is held within the eikonal approximation framework with retention in the exponent the spin operators, linear in anomalous and normal magnetic moments of the particle. The found expression for the scattering amplitude shows a contribution of the systems of anomalous and normal magnetic moments not reducible to a sum of their contributions. The problem of spin influence on the particle trajectory in the semi-classical limit is discussed.

KEY WORDS: anomalous magnetic moment, eikonal approximation, influence of the spin on trajectory.

DECAY INSTABILITY OF THE STRONG ION-ION HYBRID WAVE

D.I. Maslennikov, V.S. Mikhailenko, K.N. Stepanov

Abstract
Decay instability of strong ion-ion hybrid wave onto two ion-ion hybrid waves is considered in the case of strong pumping wave when the oscillatory velocity of particles in the pumping field may be commensurable with ion thermal velocities. Because the condition of the resonant decay is depends from the finite wave number of the pumping wave, the studies are based on the approach developed by authors, which permits the research of parametric instabilities in the case of the strong pumping with finite wave length. The excitation mechanism and growth rate of instability is derermined. The saturation level of the instability due to the frequency shift is estimated.

KEY WORDS: plasma,ion-ion hybrid wave, decay instability, growth rate, nonlinear frequency shift, saturation.
