Defects induced by electron irradiation of p-type germanium†

The calculated shapes of blocking dips differ from the experimental ones since models for charged particle motion with in crystals assume a perfect lattice. In this paper we suggest that the difference between the transverse energy distribution π(E⊥) of the particles coming out from a real crystal and that calculated in a statistical equilibrum continuum model, corrected for thermal vibration effects by a diffusion equation, accounts for crystal defects and is approximately independent of the distribution of transverse energy before diffusion and of the energy of blocked particles. The extraction of π(E⊥) from experimental dips requires the inversion of an integral equation, that is analy = tically solved in a particular case of practical interest. This would provide a way of analysing nuclear reaction time measurements that makes use of the full shape of the blocking dips. An illustrative example of the method to a blocking lifetime measurement in ²⁷A1 (p,α) ²⁴Mg resonance reactions is presented.     

Physical Foundations of Formation of Bio-Self-Organization and the Bio-Photon Emission in the Living Systems

According to elementary processes of the biological activities in the living systems with open and non-equilibrium states, which can ever exchange the energy and material and information with the environments, we have established a statistical model formed bio-self-organization, which live on the basis of the negative entropy, by the quantum statistical-theory of non-equilibrium state. From this model we have obtained the peculiar curves of changes of the energy of molecules and found out the distribution function of bio-molecules on quantum energy-levels in the living systems which are completely different from that in inorganic matters. Utilizing the curves of energy obtained we explain well the phenomenon of bio-photon emission of the bio-self-organizations found in the experiments.     

Monte Carlo study of quantitative EPMA analysis of a non‐conducting sample with a coating film

Generally, the ZAF method has been used for quantitative electron probe microanalysis (EPMA) analysis of conducting samples. However, the ZAF method is not applied to non‐conducting samples with coating films, mainly because the x‐ray intensity and the primary electron energy are both attenuated within the coating films. In this study, for application to the ZAF method we tried to correct the x‐ray attenuation and the primary electron energy attenuation by Monte Carlo simulation. As calculation models, we selected carbon coating as a light element and gold coating as heavy element and selected four kinds of materials, Al₂O₃, BN, AlN and Al₄C₃, as non‐conducting targets. After the correction we compared the calculated results and theoretical compositions. The calculated results were in good agreement with theoretical compositions. Finally, to verify the method we measured standard Al₄C₃ coated with gold (100 Å thickness). The experimental result showed good agreement with the theoretical composition. In conclusion, we confirmed that this method is useful for the quantitative analysis of non‐conducting samples with coating films. Further, by combining this method with appropriate standard compounds, we can obtain the hypothetical pure x‐ray intensities of gaseous pure elements. Copyright © 2004 John Wiley & Sons, Ltd.     

Low energy QCD predictions from non perturbative methods

We show that by using lattice results about the euclidean ?-propagator, it is possible to give theoretical predictions on the low energy behavior of thee ⁺ e ^?→had. cross section. Furthermore, we present a comparison of perturbative QCD results (plus certain sum rules corrections) with non perturbative results from the lattice in the intermediate energy region.     

Medium temperature dependence of quark energy loss

By using the reaction operator approach and the single hard scattering approximation scenario, we study the medium temperature dependence of heavy quark radiation energy loss via introducing the medium temperature into QCD running coupling α _s and Debye mass μ _D . Our results indicate that there exist an equilibrum temperature T = 320 MeV in Au-Au collisions withe energy 130 GeV at RHIC, which is agreement with the prediction from hydrodynamic model. We also find that, in the low p _t region, the color coupling effect dominates the heavy quark radiation energy loss, and the energy loss will be dominated by the Debye screening effect when the quark p _t become large.

Ionization probability of sputtered particles as a function of their energy: Part II. Positive Si ions

In this paper we represent the experimental ionization probability of sputtered silicon atoms as a function of their energy, which has been obtained for positive Si⁺ ions sputtered from silicon by O₂⁺ ion beam. To explain the experimental data, we have considered ionization of an outgoing atom at a critical distance from the surface, which occurs due to the electron transition between this atom and the surface, and suggested the formation of a local surface charge with the polarity opposite to that of the outgoing ion that has just been formed. Then we have considered the interaction between those two charges, outgoing ion, and surface charge as a process of the particle passage through a spherical potential barrier; as a result, we have obtained the theoretical energy distribution of secondary ions. Together with the well-known Sigmund-Thompson energy distribution of sputtered atoms, the obtained ion energy distribution allowed us to derive the equation for the secondary ion yield versus the sputtered particle energy. Both equations derived have exhibited a quite good correlation with our experimental results and also with a large number of published experimental data.     

Marine zone systems of higher productivity and purification using distributed energies

The present research focused on re-circulation and conversion of substance and energies for creating water environments of higher productivity and purification from the oceanic carbon and nitrogen cycle point of view. The application of distributed energies and integrated systems through the autonomous dispersion control of the environment is able to display the increase of the functions of living things and create the harmonized re-circulation of production and purification. As Japan is an island country, wave energy pumps and air-mixed jet pumps have been invented as distributed energy prime movers for these circulation systems. This paper summarizes our research and development programs and describes some current results of sea trials with prototypes.
