1. 1. Multi-Electron Coincidence Studies of Atoms and Molecules

   Författare :Egil Andersson; Raimund Feifel; Jan-Erik Rubensson; Kiyoshi Ueda; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-ionization; electron emission; time-of-flight spectroscopy; coincidence spectroscopy; core-valence ionization; synchrotron radiation; electron correlation; Atomic and molecular physics; Atom- och molekylfysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : This thesis concerns multi-ionization coincidence measurements of atoms and small molecules using a magnetic bottle time-of-flight (TOF) spectrometer designed for multi-electron coincidence studies. Also, a time-of-flight mass spectrometer has been used together with the TOF electron  spectrometer for electron-ion coincidence measurements. LÄS MER

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

   Författare :Yu-Chen Cheng; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoionization; High-order Harmonic Generation; Extreme Ultraviolet; Free-Electron Laser; Molecular Dissociation; Charge Transfer; Coincidence Measurement; Momentum Imaging; Electron Wave Packet; Fysicumarkivet A:2019:Cheng;

   Sammanfattning : 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.

4. 3. Fragmentation studies of small molecules using synchrotron radiation

   Författare :Emilio Melero García; KTH; []
   Nyckelord :Coincidence; fragmentation;

   Sammanfattning : This thesis presents experimental data on the fragmentationof gas phase sulfur hexafluoride (SF6) and deutheromethane(CD4) molecules after their interaction with synchrotronradiation in the energy range of 70-200 eV. The data wasobtained using coincidence spectroscopy between energy resolvedelectrons and ions (EREICO). LÄS MER

5. 4. Osannolika händelser och den svenska realistiska romanen : Ett estetiskt och existentiellt bekymmer

   Författare :KENNETH LINDEGREN; Litteraturvetenskap; []
   Nyckelord :Swedish fiction; causality; tellability; coincidence; chance; improbability; fiction-technique; realism; 20th century; 19th century; Carl Jonas Love Almqvist; Fredrika Bremer; Victoria Benedictsson; Hjalmar Söderberg; Willy Kyrklund; Per Gunnar Evander; Svensk fiktion; kausalitet; berättarbarhet; sammanträffande; slump; osannolikhet; berättarteknik; realism; 1900-talet; 1800-talet; Carl Johan Love Almqvist; Fredrika Bremer; Victoria Benedictsson; Hjalmar Söderberg; Willy Kyrklund; Per Gunnar Evander;

   Sammanfattning : This thesis deals with improbable events in the realistic novel. The overarchingidea is that realism is distinguished by dealing with improbable events on thebasis of a double perspective: both as an existential and as an aesthetic problem. LÄS MER
