[en] One studies interaction of channeled particles with equal charge to mass ratio. Application of the perpetual potential approximation and of its oscillating representation enables to separate wave function of the system centre of mass. One solved numerically equation for wave function of relative motion at low energy values - passing through a two-dimensional potential barrier. It is shown that no passing through the barrier is seen, the basic components in a reflected wave corresponds to an incident one

[en] When Ernest Rutherford became Professor of Physics at Manchester University in 1907, he brought with him the research field in which he had played a leading role over the previous few years: radioactivity. Rutherford turned the Manchester physics lab over to studies of radioactivity and radiation, and through his own work and that of his many collaborators and students, established Manchester as a major international centre in atomic physics. It was out of this powerhouse that the nuclear theory of the atom emerged in 1911. In 1917, Rutherford 'disintegrated' the nitrogen nucleus using α-particles, opening up the possibility of nuclear structure. At Cambridge's Cavendish Laboratory from 1919, Rutherford and his co-workers began to explore the constitution of the nucleus. With Chadwick, Aston and others, Rutherford turned his research school to the emergent field of nuclear physics – a field he dominated (though not without controversy) until his death in 1937. Exploring the intellectual, material and institutional cultures of early twentieth century physics, this paper will outline the background to Rutherford's career and work, the experimental and theoretical origins of nuclear theory of the atom and the early development of nuclear physics.

[en] Results are presented from experimental studies of the parameters of two counterpropagating (colliding) plasma flows generated by discharges in crossed electric and magnetic fields. It is shown that the conversion efficiency of the energy deposited in the discharges into the energy of directed plasma flows is 0.3-0.6. For discharge current pulses with a duration of ∼10 μs, the energy flux density in the plasma flow reaches ∼10 J/cm² and the total energy of the flow is on the order of 300 J. The density of deuterons in the flows is ∼10¹⁵ cm^-3, and the flow velocity is ≤ 2 x 10⁷ cm/s. The total number of particles carried by the flows is about 10¹⁹. The possibility of using counterpropagating plasma flows to study reactions involving light nuclei (dd, pd, dt, and dHe reactions) in the range of ultralow collision energies is discussed

[en] In this talk a set of our recent measurements using low energy proton beams to address different problems in nuclear structure studies and nuclear astrophysics are presented. The first part of the talk covers measurements of capture cross sections and astrophysical S factors for p("1"0B, "7Be)α, p("1"0B, "1"1C)γ reactions

[en] Recently we have analyzed the α-nucleus elastic scattering in the energy range 25-70 MeV/nucleon within the framework of the Coulomb modified Glauber model. The results show specifically the importance of large q components of the NN amplitude to providing a satisfactory explanation of the α-α elastic angular distribution up to fairly large value of momentum transfer. Motivated by the success of the Glauber model at projectile energy as low as 25 MeV/nucleon, we, in this work consider the analysis of ³He-nucleus reaction cross section (σR) data at 96.4, 137.8, 167.3 MeV. Our aim is to see how far the NN amplitude, used, could be helpful in the analysis of the ³He-nucleus reaction cross section at energies under consideration and what could be inferred about the behavior of the NN amplitude from the point of view of providing the simultaneous description of the elastic angular distribution and σR at relatively lower energies

[en] A new state of atomic clusters can be easily generated by electric discharges. Since Electro-Nuclear Reactions (ENRs) could occur in the cluster, new physics could be expected with an accelerated beam of the clusters. Here, two acceleration methods of the clusters will be proposed by using linac.(author)

[en] The electron screening effect in the d(d,p)t reaction has been studied at the Ruhr-Universitaet Bochum for most of the metals (57) and some insulators/semiconductors by using deuterated targets. The deuterated targets were produced via implantation of low-energy deuterons. As compared to measurements performed with a gaseous D₂ target, a large effect has been observed for all metals. In particular work has been done to investigate the high solubility (y(T) ≥ 1) for the metals of groups III and IV and the lanthanides, at a sample temperature T= 200 deg C. The hydrogen solubility in the samples dropped to a level of few percent (compared to T ∼ 20 deg C) and a large screening became thus observable. An explanation of the large effect in metals is provided by the plasma model of Debye applied to the quasi-free metallic electrons. A first evidence of the applicability of Debye's model is that the deduced number of free electrons per metallic atom (n_eff) agrees with the calculated number from the Hall coefficient, for all metals investigated. A critical test of the classical Debye model is the temperature dependence U_e ∝ T^-1/2 and new results will be presented. Besides, because of the hydrogen solubility can be changed varying the temperature of the sample we measured the screening effect for the deuterated metal Ti as a function of sample temperature, at T = -10 deg C to 200 deg C. Above 50 deg C the hydrogen solubility dropped to value far below 1 and a large screening effect became observable. Thereafter, assuming the temperature-dependent solubility y(T) affects directly n_eff one obtains: U_e ∝ √1-y(T). I will report on such studies some preliminary results. (author)

[en] Polarization effects in the deuteron inelastic scattering on nuclei in the vicinity of resonance with the mass of ∼ 2190 MeV/c² excitation have been analyzed in the framework of impulse approximation. It has been shown that the spin-dependent part of the NN → NN* (2190) process amplitude plays a significant role at large transferred momenta. Predictions for a number of polarization observables as well as for the spin-flip cross sections have been obtained
