We formulate a general hybrid quantum-classical technique to describe the interaction of diatomic molecules with XUV pulses. demonstrate accuracy our model in context <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:msub><a:mi mathvariant="normal">O</a:mi><a:mn>2</a:mn></a:msub></a:math> molecule an pulse photon energy ranging from 20–42 eV. account for electronic structure and electron ionization quantum mechanically employing accurate molecular continuum wave functions. motion...
We obtain continuum molecular wavefunctions for open-shell molecules in the Hartree-Fock framework. do so while accounting singlet or triplet total spin symmetry of ion, that is, orbital and initial where electron ionizes from. Using these wavefunctions, we dipole matrix elements a core due to single-photon absorption by linearly polarized x-ray pulse. After ionization from pulse, control streak dynamics using circularly infrared (IR) For high-intensity IR pulse photon energies close...
We theoretically demonstrate a one-to-one mapping between the direction of electron ionization and phase delay linearly polarized vacuum ultraviolet (VUV) circular infrared (IR) laser pulse. To achieve this, we use an ultrashort VUV pulse that defines moment in time space when above-threshold is released IR The can then be accelerated to high velocities escaping completely determined by two pulses. dipole matrix element transition from initial bound state ${\mathrm{N}}_{2}$ molecule,...
