Circular Dichroism in Atomic Resonance-Enhanced Few-Photon Ionization
A. H. N. C. De Silva, T. Moon, K. L. Romans +8
We investigate few-photon ionization of lithium atoms prepared in the polarized 2() state when subjected to femtosecond light pulses with left- or right-handed circ…
Positive-energy spectra of atomic hydrogen in a magnetic field with an adiabatic-basis-expansion method
L. B. Zhao, K. D. Wang, K. Bartschat
The problem of photoionization of atomic hydrogen in a white-dwarf-strength magnetic field is revisited to understand the existing discrepancies in the positive-energy spectra obta…
Photoelectron spectroscopy of laser-dressed atomic helium
Severin Meister, Aaron Bondy, Kirsten Schnorr +10
Photoelectron emission from excited states of laser-dressed atomic helium is analyzed with respect to laser intensity-dependent excitation energy shifts and angular distributions.…
Ellipticity Dependence of Excitation and Ionization of Argon Atoms by Short-Pulse Infrared Radiation
Thomas Pauly, Aaron Bondy, Kathryn R. Hamilton +4
When atoms or molecules are exposed to strong short-pulse infrared radiation, ionization as well as "frustrated tunneling ionization" (FTI) can occur, in which a portion of the alm…
Observation of Dynamic Stark Resonances in Strong-Field Excitation
Dashavir Chetty, Rohan D. Glover, Bruno A. deHarak +12
We investigate AC Stark-shifted resonances in argon with ultrashort near-infrared pulses. Using 30 fs pulses we observe periodic enhancements of the excitation yield in the intensi…
Electron-impact excitation and ionization of atomic calcium at intermediate energies
Oleg Zatsarinny, Henry Parker, Klaus Bartschat
We present a comprehensive study of electron collisions with calcium atoms by using the convergent \emph{B}-spline \emph{R}-matrix method. Elastic, excitation, and ionization cross…
