Strong Field Ionization Of Radicals And Reaction Intermediates
… The calculated Isats correlate closely with the ionization potential which will help identify the different isomers. This study was then extended to several precursors relevant to combustion. The flash pyrolysis spectra are also presented. The calculated Isats for the heptane and isomers products …

Fundamental Studies And Applications Of Strong Field Ionization
<p>In an intense laser field, atoms and molecules experience tunneling ionization directly to the continuum. We used this method to study several aspects and applications of strong field ionization (SFI) in atoms and molecules. One study used SFI to probe the photofragments produced by …

Developing A Toolbox To Probe Reaction Dynamics With Strong Field Ionization And Non-Linear Attosecond Spectroscopy
… related to the laser matter interaction: strong field ionization and nonlinear attosecond spectroscopy. The first part is based on the studies related to the strong field ionization probe. Strong field ionization probe was verified to be sensitive to the sign of magnetic quantum number …

Quantum Dynamics of Strong Field Light-Matter Interactions
… models for the light-matter interactions in the strong-field regime. These investigations provided us with valuable insights into long-debated problems related to quantum tunneling, namely, the quantum tunneling time and momentum i.e., the ongoing debate in the literature about how much time a …

Following a Photochemical Reaction of Br2 using Photoion and Photoelectron Momentum Spectroscopy
… cycles by using orthogonal two-color laser Fields. Then we introduce a semiclassical model for simulating both atomic and molecular photoelectron spectra.. For atomic ionization, various of interference structures are comprehensively studied. In particular, we investigate the origin of …

Time-dependence of ionization and excitation by intense, short electric pulses
… thesis studies of time-dependent electric pulse ionization and excitation of atomic systems (the hydrogen atom and its negative ion) are performed. Unidirectional (half-cycle) pulses are considered, as well as oscillating (up to several-cycle) pulses. The time scale of the pulses considered …
