Harmonic generation of noble-gas atoms in the Near-IR regime using ab-initio time-dependent R-matrix theory
O. Hassouneh, A. C. Brown, H. W. van der Hart
We demonstrate the capability of ab-initio time-dependent R-matrix theory to obtain accurate harmonic generation spectra of noble-gas atoms at Near-IR wavelengths between 1200 and…
Electron dynamics in the carbon atom induced by spin-orbit interaction
H. F. Rey, H. W. van der Hart
We use R-Matrix theory with Time dependence (RMT) to investigate multiphoton ionization of ground-state atomic carbon with initial orbital magnetic quantum number =0 and …
Population trapping in bound states during IR-assisted ultra-fast photoionization of Ne
H. W. van der Hart, R. Morgan
We have investigated photoionization of Ne in the combined field of a short infra-red laser pulse and a delayed ultra-short pulse of the infra-red laser's 23 harmonic.…
Time-dependent R-matrix theory applied to two-photon double ionization of He
H. W. van der Hart
We introduce a time-dependent R-matrix theory generalised to describe double ionization processes. The method is used to investigate two-photon double ionization of He by intense X…
Multichannel Interference In High-Order Harmonic Generation From Ne(+) Driven By Ultrashort Intense Laser Pulse
O. Hassouneh, A. C. Brown, H. W. van der Hart
We apply the time-dependent R-matrix method to investigate harmonic generation from Ne(+) at a wavelength of 390 nm and intensities up to 10(15) Wcm(-2). The 1s(2)2s(2)2p(4) (3)P(e…
