We report the direct observation of interference effects in a Young's double-slit experiment where interfering waves are two spatially separated components de Broglie wave single 1.3 MeV hydrogen atoms formed close to either target nucleus H++H2 electron-transfer collisions. Quantum strongly influences results even though have wavelength, lambda_{dB}, as small 25 fm.
We report experimental angular differential cross sections for nonradiative single-electron capture in $p$-He collisions ($p+$ He $\ensuremath{\rightarrow}$ H $+$ He${}^{+}$) with a separate peak at the $0.47$ mrad Thomas scattering angle energies $1.3--12.5$ MeV range. find that intensity of this scales projectile velocity as ${v}_{\mathrm{P}}^{\ensuremath{-}11}$. This constitutes first test prediction from 1927 by L. H. [Proc. R. Soc. 114, 561 (1927)]. At our highest energy, contributes...
Abstract In the present work our experimental results on energy shifts and widths (full width of half‐maximum) quasi‐elastic peaks (1–5 keV) obtained using a high‐energy‐resolution electron spectrometer different (C, Si, Ni Au) surfaces are compared with those calculated by assuming single elastic scattering free atoms having Maxwell–Boltzmann thermal velocity distribution. There is good agreement in case as well for broadenings higher atomic number polycrystalline samples (Ni, Au). however,...
Abstract The energy distribution of electrons backscattered elastically from polyethylene is studied. separation between the carbon and hydrogen peak in shown. Furthermore, effect multiple scattering on shifts Doppler broadenings determined using Monte Carlo (MC) simulations. Our MC simulations are good agreement with our experimental observations.

We present experimental kinetic-energy-release distributions in the asymmetric fission processes $\mathrm{C}_{60}{}^{q+}\ensuremath{\rightarrow}\mathrm{C}_{58}{}^{(q\ensuremath{-}1)+}+\mathrm{C}_{2}{}^{+}$ and $\mathrm{C}_{70}{}^{q+}\ensuremath{\rightarrow}\mathrm{C}_{68}{}^{(q\ensuremath{-}1)+}+\mathrm{C}_{2}{}^{+}$ for highly excited mother ions charge states $q=4--8$. find that $\mathrm{C}_{70}{}^{q+}$ are considerably narrower peak at lower energies than $\mathrm{C}_{60}{}^{q+}$...
High-energy resolution $K{L}_{23}{L}_{23}$ Auger spectra of polycrystalline Cu and Ni metals were measured while tuning the energy exciting x-rays in near threshold region up to $50\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ above $K$ absorption edge. The intensity evolution pronounced satellite lines as a function photon reveals different behavior for particular satellites consequence initial state final shake excitations. development is compared predictions simple models based on free atom...
Abstract In the quantitative analysis of buried interfaces or exploration local electronic structures around component atoms in bulk solids, spectroscopy transitions deep atomic core has an increasingly significant role to play. A key issue understanding photoelectron spectra is identification and separation contributions that are attributable different excitations leading loss energy emitted photoelectrons. this work, Ge 1s 2s analyzed using various models interpret measured spectral...
We report on measurements of transfer excitation in collisions 0.3-1.3 MeV protons with spatially oriented H2 molecules. Evidences two center interference are found the angular distribution molecule after a process and directly projectile scattering distributions. These features can be explained way which is analogous to that for interferences Young's classical double slit experiment: The fast projectiles preferentially capture electrons close either molecular nuclei, thereby they change...
Abstract Evolution of the photoionized KLL Auger satellite line for 3 d transition metals was studied. The intensity ratio relative to main 1 D 2 (KL L ) diagram measured Cu and Ni as a function incident photon energy theoretical models based on adiabatic approximation were fitted experimental data. Thomas model, Vatai model Roy et al . considered. In addition, we modified developed new model. Comparison these four made their difference discussed. Copyright © 2009 John Wiley & Sons, Ltd.
Auger electron lineshapes after impact inner-shell ionization of argon at 500 eV primary energy are studied by the (e, 2e) coincidence technique. Emitted electrons detected in with ionizing scattered and slow PCI inducer ejected is calculated from conservation. In particular, strongly asymmetric sharing, this means effect very low (i.e. 0–5 eV) electrons, measured compared calculations. The opposite case (equal sharing) also studied.
We have studied the stabilities of multiply charged van der Waals dimers in slow Xe30+ + [C60]2([C60C70], [C70]2) → Xe(30-s)+ [C60]2r+([C60C70]r+, [C70]2r+) (r-s)e-electron-transfer collisions (v = 0.4 a.u. and r ≤ 7). The relative ionization cross sections display even-odd variations as functions for [C60]2r+, [C60C70]r+, [C70]2r+. This is clear contrast to typical smooth decreasing behavior multiple fullerene monomers, which can be explained within framework classical over-the-barrier...
