Photoassociative Spectroscopy Of Ultracold Argon And Krypton Confined In A Magneto Optical Trap, Maha Khaled Omar
Photoassociative Spectroscopy Of Ultracold Argon And Krypton Confined In A Magneto Optical Trap, Maha Khaled Omar
Physics Theses & Dissertations
Creating ultracold molecules has attracted considerable interest in the last decade. Once created, such molecules can be used for precision spectroscopy or to study chemical reactions at ultracold tem peratures. Several techniques have been developed to produce ultracold molecules; the most common is photoassociation where two ultracold atoms collide in the presence of light that induces a free-bound transition to an excited molecular state. Photoassociation can also be used to perform spectroscopy in order to map out the ro-vibrational levels of a molecular state. In this dissertaiotn, we report on our Photoasociative Spectroscopy (PAS) studies conducted separately in argon and …
Catalysis Of Stark-Tuned Interactions Between Ultracold Rydberg Atoms, Aye Lu Win
Catalysis Of Stark-Tuned Interactions Between Ultracold Rydberg Atoms, Aye Lu Win
Physics Theses & Dissertations
We present the study of the catalysis effect in the resonant energy transfer between ultracold 85Rb Rydberg atoms. We have investigated the energy transfer process of 34p + 34p → 34s + 35s, and observed Stark-tuned Forster resonances. When additional Rydberg atoms of 34d state are included in the interaction, an increase in the population of 34s states atoms is observed. Although the 34d state atoms do not directly participate in the resonant energy transfer that produces 34s state atoms, they add an additional interaction channel 34p + 34 …
