Photoelectron Angular Distributions of Nonresonant Two-Photon Atomic Ionization Near Nonlinear Cooper Minima
J. Hofbrucker, L. Eiri, A. V. Volotka +1
Photoelectron angular distributions of the two-photon ionization of neutral atoms are theoretically investigated. Numerical calculations of two-photon ionization cross sections and…
Enhanced polarization transfer to the characteristic x-ray lines near the nonlinear Cooper minimum of two-photon ionization
J. Hofbrucker, A. V. Volotka, J. Szlachetko +1
It has been shown that for nonlinear atomic ionization, transfer of the degree of circular polarization from incident to fluorescence light is maximum at the Cooper minimum (see Ph…
Breakdown of the electric dipole approximation at Cooper minima in direct two-photon ionisation
J. Hofbrucker, A. V. Volotka, S. Fritzsche
We predict breakdown of the electric dipole approximation at nonlinear Cooper minimum in direct two-photon shell atomic ionisation by circularly polarised light. According to p…
Fluorescence polarization as a precise tool for understanding nonsequential many-photon ionization
J. Hofbrucker, A. V. Volotka, S. Fritzsche
Nonsequential two-photon ionization of inner-shell subshell of neutral atoms by circularly polarized light is investigated. Detection of subsequent fluorescence as a signature…
Maximum Elliptical Dichroism in Atomic Two-Photon Ionization
J. Hofbrucker, A. V. Volotka, S. Fritzsche
Elliptical dichroism is known in atomic photoionization as the difference in the photoelectron angular distributions produced in nonlinear ionization of atoms by left- and right-ha…
Photoelectron distribution of non-resonant two-photon ionization of neutral atoms
J. Hofbrucker, A. V. Volotka, S. Fritzsche
Photoelectron angular distributions following the non-resonant two-photon K-shell ionization of neutral atoms are studied theoretically. Using the independent particle approximatio…
