[en] Cross section data in the energy range above 1 eV have been critically evaluated for electron impact collision processes involving the impurity species (CO, CO₂, and H₂O) most relevant to low-temperature plasmas. A short review of the cross section measurements is given for each collision process. The literature has been surveyed up to December 1999. Analytic fits to the recommended cross sections are also presented

[en] Cross sections for 138 processes in collisions of electrons with hydrocarbons, based on available literature sources, are critically compiled. The literature has been surveyed up to September 2000. A short comment is given for each measurement. The recommended data sets are presented in separate graphs for each process. Analytic fits to the recommended cross sections are also presented

[en] Recent works associated with the innershell ionization in heavy ion-atom collisions are reviewed. In the first part, the mechanism of the innershell ionization is discussed for three different situations of relative velocity of the incident ion and the innershell electrons. The X-ray and the Auger electron spectra due to the collision of heavy ions are discussed in detail in the second part. Many examples of X-ray spectra obtained under various situations are presented. Transitions between quasi-molecular orbits and the life of innershell vacancies are treated in the third and fourth parts. The emission of various types of bremsstrahlung is treated in the fifth part. Finally, the application of the innershell ionization phenomena to the ultra-microchemical analysis is reviewed as an example of applications. (Aoki, K.)

[en] In EBIS (electron beam ion source) and EBIT (electron beam ion trap) which is its variation developed recently, by the spatial charge potential that the very high density electron flow converged with a strong magnetic field makes, the ions formed radially are confined, and by electrostatic field potential, axial ions are confined, by this means, it is attempted to obtain the multi-charge ions through the step by step ionization by the collision with high energy electrons many times. The large difference between both is whereas ionization occurs along the drift tube arranged in about 1 m in EBIS, in EBIT, ions are trapped in a short region of 1 - 2 cm. In order to make relatively heavy ions, ions must be confined for a considerably long time, and ultrahigh vacuum is required for an ion source. Ions are heated with the progress of ionization, and the confinement for a long time becomes difficult, accordingly, heavy ions are cooled by introducing light, low charge ions. The experiment using the ion beam of EBIS/EBIT is reviewed. The observation of the ion beam taken out from an ion source and the direct observation of ions inside an ion source are described. (K.I.)

[en] The secondary electron emission yields, γ^-, and the secondary positive ion emission yields, γ⁺, from various non-metallic (perovskite type) targets induced by low-energy ion impact have been measured under ultra-high vacuum (∼10^-11 Torr) conditions. It has been found that the observed γ^- from the non-metallic surfaces is proportional to the electronic stopping power over the whole impact energy range investigated. But the proportional coefficients in γ^- are found to be 2-3 times larger than those for metal targets. We have observed, for the first time, that γ^- strongly depends on the incident ion beam flux and becomes zero above a critical ion flux for some targets. We have also found that the observed γ⁺ from non-metallic surfaces under Ar⁺ ion impact is far large compared with the calculated results and, unexpectedly, is proportional to the electronic stopping power but not to the nuclear stopping power. Furthermore, it is shown that, under high incident ion fluxes, these emitted ions have large kinetic energy, almost comparable to the incident ion energy, which can be due to local charge-accumulation formed through the interactions with the incident ions on the non-metallic surfaces
