  2. 2. Ultrafast Photoionization Dynamics Studied with Coincidence Momentum Imaging Spectrometers

    Author : Yu-Chen Cheng; Atomfysik; []
    Keywords : Photoionization; High-order Harmonic Generation; Extreme Ultraviolet; Free-Electron Laser; Molecular Dissociation; Charge Transfer; Coincidence Measurement; Momentum Imaging; Electron Wave Packet;

    Abstract : The time scale of the dynamics in atoms and molecules varies from attoseconds (10-18) to picoseconds (10-12) depending on the size of the particles. To study such dynamics, ultrafast light pulses are needed to trigger and capture the reaction. One of the most direct methods consists in ionizing the system and observing the following response.

  3. 3. Development of infrared spectroscopy techniques for environmental monitoring

    Author : Jonas Sandsten; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; environmental pollution measurements; infrared spectrometers; diffraction and scattering; absorption spectroscopy; remote sensing; ray tracing; image processing; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2000:Sandsten;

    Abstract : Infrared spectroscopy techniques have long been utilized in identifying and quantifying species of interest to us. Many of the elementary molecules in the atmosphere interact with infrared radiation through their ability to absorb and emit energy in vibrational and rotational transitions. READ MORE
