The process of radiative electron capture (REC) in relativistic collisions high-Z ions with low-Z gaseous and solid targets is studied experimentally theoretically. observed x-ray spectra are analyzed respect to photon angular distributions as well total K-REC cross sections. experimental results for angle-differential sections reproduced by exact calculations which yield significant deviations from standard ${\mathrm{sin}}^{2}$\ensuremath{\theta} distributions. Total shown follow a simple...
The energy levels and spectral lines of gallium atom in all stages ionization have been compiled. Experimental data on exist for spectra Ga I through VII, XIII XXVI, XXX. For Li-like XXIX H-like XXXI, theoretical line wavelengths are I, II, III we include radiative probabilities electric-dipole transitions where available. XV XX, XXIII XXX, magnetic-dipole electric-quadrupole included. ground state configuration term a value included each ion.
Energy levels, wavelengths, and transition probabilities of the first second spectra tungsten, W I II, have been compiled. Wavelengths observed transitions energy levels derived from those wavelengths obtained a critical evaluation available literature. Measured for some compiled published

Beam stopping cross section and shine-through for neutral hydrogen beam injection into fusion plasmas have been calculated by using recommended sections presently available atomic processes including multistep collision involving excited states. The thus obtained agrees well with recent experiments of JT-60U. present calculations show that the play a crucial role in high-energy beams high-density plasmas. Analytical fits to fitting parameters are also presented plasma impurities nuclear...
In high-energy atomic collisions between bare high- $Z$ projectiles and low- target atoms, an electron may be captured radiatively into excited projectile state which subsequently decays by x-ray emission. This process is the inverse of two-photon--one-electron ionization, in first photon resonantly excites from hydrogenic ${1s}_{1/2}$ ground a second ionizes electron. We present experimental theoretical study angular distribution Ly- ${\ensuremath{\alpha}}_{1}$ (...
A detailed discussion is given of the general behavior differential cross sections for radiative electron capture in relativistic and nonrelativistic heavy-ion--atom collisions. From angular-momentum conservation a simple approximate treatment, basic qualitative features can be derived an analytic form. Subsequently, results rigorous calculations are presented graphically sequence projectile charges energies. It shown that capture, influence spin manifests itself particularly clear-cut way.
The photon angular distributions for radiative electron capture (REC) into the $j=\frac{1}{2}$ and $j=\frac{3}{2}$ $L$ subshell levels were measured calculated ${\mathrm{U}}^{90+}$ \ensuremath{\rightarrow} C collisions at 89 MeV/u. experiment provides first study of distribution REC a projectile $p$ state ($j=\frac{3}{2}$) which was found to exhibit slight backward peaking in laboratory frame.

In high-energy atomic collisions between bare high-$Z$ projectiles and low-$Z$ target atoms, an electron may be captured radiatively into the ground state or, alternatively, excited projectile state, which subsequently decays by x-ray emission. These processes are inverse of a single-step or two-step ionization, in first photon resonantly excites from hydrogenic ${1s}_{1/2}$ second ionizes electron. this paper, we present theoretical analysis with particular emphasis on detailed multipole...
In high-energy atomic collisions between bare high-Z projectiles and low-Z target atoms, an electron may be captured radiatively into the projectile [radiative capture (REC)]. The photon angular distributions can very well represented by radiative recombination (RR) of with free electrons. This process is inverse photoelectric effect. this paper, we present exact differential RR cross sections for ${\mathrm{Au}}^{79+}$ ${\mathrm{U}}^{92+}$ at energies 0.2, 0.5, 1, 2, 5, 10 GeV/u. We also...
Antihydrogen formation cross sections are calculated for low-energy collisions of antiproton with positronium by the hyperspherical coupled-channel method. The scattering wavefunctions expanded in terms a large number sector-adiabatic states associated n=1-4 antihydrogen and n=1-3 asymptotic separated-atom region. present differ considerably from those unitarized Born approximation reported Mitroy Stelbovics (1994). disagreement becomes larger decreasing collision energy owing to different...
We perform an extension of the continuum-distorted-wave (CDW) approximation for single electron capture by introducing model potentials to describe interaction active with residual-target and projectile ions. The cross sections transfer in collisions bare dressed ions H He atoms are calculated compared experimental data previous CDW calculations that make use approximate analytical wave functions represent initial final states. For proton-He into definite states present better agreement...
Congenital prepubic sinus (CPS) is an extremely rare anomaly, which often associated with purulent discharge from a midline opening overlying the pubis. CPS was first described by Campbell et al. in 1987 and they suggested that it might represent variation normal embryological development. Several theories have been proposed regarding pathogenesis of CPS. However, etiology still unclear because anatomical pathological features differ each other. We report case review literature to improve...
