Spatial and temporal distribution of a 1-MeV proton microbeam guided through a poly(tetrafluoroethylene) macrocapillary
G. U. L. Nagy, Z. T. Gaál, I. Rajta +1
We present computer simulations about the spatial and temporal evolution of a 1-MeV proton microbeam transmitted through an insulating macrocapillary with the length of 45 mm and w…
Interaction of antiproton with helium based on ab-initio calculations
Imre Ferenc Barna, Mihály András Pocsai, Károly Tőkési
We present ionization cross sections for antiproton and helium collisions based on ab-initio time-dependent coupled channel method. In our calculations a finite basis set of regula…
Electron correlations in the antiproton energy loss distribution in He
S. Borbély, X. -M. Tong, S. Nagele +6
We present ab-initio calculations of the electronic differential energy transfer (DET) cross-sections for antiprotons with energies between keV and MeV interacting with heliu…
Semiclassical two-step model for ionization of hydrogen molecule by strong laser field
N. I. Shvetsov-Shilovski, M. Lein, K. Tőkési
We extend the semiclassical two-step model for strong-field ionization that describes quantum interference and accounts for the Coulomb potential beyond the semiclassical perturbat…
Absolute Determination of Optical Constants by a Direct Physical Modeling of Reflection Electron Energy Loss Spectra
H. Xu, B. Da, J. Toth +2
We present an absolute extraction method of optical constants of metal from the measured reflection electron energy loss (REELS) spectra by using the recently developed reverse Mon…
Correlations between the final momenta of electrons and their initial phase-space distribution in the process of tunnel ionization
Viktor Ayadi, Peter Foldi, Peter Dombi +1
We present both full quantum mechanical and semiclassical calculations of above threshold ionization (ATI) of a hydrogen atom in the tunneling regime by a few-cycle linearly polari…
Ionization of atoms by few-cycle EUV laser pulses: carrier-envelope phase dependence of the intra-pulse interference effects
A. Tóth, S. Borbély, K. Tőkési +1
We have investigated the ionization of the H atom by intense few-cycle laser pulses, in particular the intra-pulse interference effects, and their dependence on the carrier-envelop…
Experimental Setup for Studying Guiding of Proton Microbeam

We present the design and construction of our experimental setup for studying the transmission of proton microbeam through a single, cylindrical shape, macroscopic insulating capil…
Ionization of helium by slow antiproton impact: total and differential cross sections
S. Borbély, J. Feist, S. Nagele +3
We theoretically investigate the single and double ionization of the He atom by antiproton impact for projectile energies ranging from ~keV up to ~keV. We obtain accurate…
Probing scattering phase shifts by attosecond streaking
Renate Pazourek, Stefan Nagele, Katharina Doblhoff-Dier +4
Attosecond streaking is one of the most fundamental processes in attosecond science allowing for a mapping of temporal (i.e. phase) information on the energy domain. We show that o…
Time-resolved photoemission by attosecond streaking: extraction of time information
Stefan Nagele, Renate Pazourek, Johannes Feist +4
Attosecond streaking of atomic photoemission holds the promise to provide unprecedented information on the release time of the photoelectron. We show that attosecond streaking phas…

First time-resolved photoemission experiments employing attosecond streaking of electrons emitted by an XUV pump pulse and probed by a few-cycle NIR pulse found a time delay of abo…
