Cold Target Recoil Ion Momentum Spectroscopy: a &momentum microscope' to view atomic collision dynamics
Reinhard Dörner,V. Mergel,Ottmar Jagutzki,Lutz Spielberger,Joachim Ullrich,R. Moshammer,Horst Schmidt-Böcking +6 more
TL;DR: The cold target recoil ion momentum spectroscopy (COLTRIMS) is a momentum space imaging technique for the investigation of the dynamics of ionizing ion, electron or photon impact reactions with atoms or molecules as mentioned in this paper.
Journal ArticleDOI
Recoil-ion momentum spectroscopy
Joachim Ullrich,R. Moshammer,Reinhard Dörner,Ottmar Jagutzki,V. Mergel,Horst Schmidt-Böcking,Lutz Spielberger +6 more
TL;DR: In this article, high-resolution recoil-ion momentum spectroscopy (RIMS) is used to determine the charge state and the complete final momentum vector of a recoiling target ion emerging from an ionizing collision of an atom with any kind of radiation.
Journal ArticleDOI
Correlated electron emission in multiphoton double ionization
Th. Weber,Harald Giessen,M. Weckenbrock,G. Urbasch,André Staudte,Lutz Spielberger,Ottmar Jagutzki,V. Mergel,M. Vollmer,Reinhard Dörner +9 more
TL;DR: A strong correlation is reported between the magnitude and the direction of the momentum of two electrons that are emitted from an argon atom, driven by a femtosecond laser pulse (at 38 TW cm-2).
Journal ArticleDOI
Multiple hit read-out of a microchannel plate detector with a three-layer delay-line anode
Ottmar Jagutzki,Alfred Cerezo,A. Czasch,Reinhard Dörner,M. Hattass,M. Huang,V. Mergel,U. Spillmann,K. Ullmann-Pfleger,Th. Weber,H. Schmidt-Bocking,George Davey Smith +11 more
TL;DR: In this paper, a delay-line read-out technique for microchannel plate detectors with an increased acceptance for multiple hit events compared to standard two-layer delayline anodes is presented.
Journal ArticleDOI
Recoil-Ion momentum distributions for single and double ionization of helium in strong laser fields
Th. Weber,M. Weckenbrock,André Staudte,Lutz Spielberger,Ottmar Jagutzki,V. Mergel,F. Afaneh,G. Urbasch,M. Vollmer,Harald Giessen,Reinhard Dörner +10 more
TL;DR: The momentum distributions of singly and doubly charged helium ions created in the focus of 220 fs, 800 nm laser pulses at intensities of (2.9-6.6)x10(14) W/cm(2) are measured.
