The spectrum of the luminous aureole near the calcium target radiated by excited particles ejected from its surface by a beam of Ar+ ions (energy 30 keV, current density 200 μA/cm2) was investigated. This spectrum contains lines of the singlet and t

The vacuum-UV spectrum of a krypton supersonic jet excited by an electron beam was studied. Three continua with intensity maxima at λ = 1250 A, 1480 A and 2260 A were observed in the spectral region 1100–2300 A. Two of them at λ = 1250 A and 2260

The T 0 /ϱ( T 0 ) dependences ( T 0 is the intensity of the 1920 A continuum at its maximum, ϱ is the concentration of argon atoms at the intersection of an electron beam and a jet, T 0 is the temperature of argon at the nozzle) for the 1920 A cont

A brief account of the properties of the ion—ion emission phenomenon is given. The possibilites of applying this phenomenon to the study of processes on the surface and in the bulk of solids are discussed. The foundations of the new method are cons

The radiation emitted by particles ejected by inert gas ions from the surface of 25 solid targets was investigated. It was shown that continuum radiation was emitted by particles ejected from targets of transition elements with unfilled nd-shells. Fo

In the argon L 2,3 X-ray spectrum excited by an electron beam, a group of lines was detected in the region of 250–270 eV. The 250 eV line was attributed to the n d → 2p and n s → 2p transitions within excited neutral atoms of 1s 2 2s 2 2p 5 3s

The emission spectrum of a polymer film formed on a metallic target bombarded by Ne + ions is compared with the absorption spectrum of the Ne 2 molecule. From this comparison follows that the emission spectrum of the polymer film is the spectrum of t

The critical currents of indium films irradiated by helium ions were measured. An effect of irradiation on jc (H⊥) characteristics was stated. This effect is due to the change of the degree of a disorder in a substance of the irradiated film.
