Annihilation-Gamma-based Diagnostic Techniques for Magnetically Confined Electron-Positron Pair Plasma
J. von der Linden, S. Nißl, A. Deller +6
Efforts are underway to magnetically confine electron--positron pair plasmas to study their unique behavior, which is characterized by significant changes in plasma time and length…
Slow decay processes of electrostatically trapped Rydberg NO molecules
A. Deller, M. H. Rayment, S. D. Hogan
Nitric oxide (NO) molecules initially traveling at 795 m/s in pulsed supersonic beams have been photoexcited to long-lived hydrogenic Rydberg-Stark states, decelerated and electros…
Excitation and characterization of long-lived hydrogenic Rydberg states of nitric oxide
A. Deller, S. D Hogan
High Rydberg states of nitric oxide (NO) with principal quantum numbers between 40 and 100 and lifetimes in excess of 10 s have been prepared by resonance enhanced two-color two…
Microwave spectroscopy of the fine structure of high Rydberg states in He
A. Deller, S. D. Hogan
The fine structure of high Rydberg states in helium has been measured by microwave spectroscopy of single-photon transitions from $1\mathrm…
Confinement of high- and low-field-seeking Rydberg atoms using time-varying inhomogeneous electric fields
A. Deller, S. D. Hogan
Helium atoms in high- and low-field-seeking Rydberg states with linear and quadratic Stark shifts have been confined in two dimensions and guided over a distance of 150 mm using ti…
SSPALS: a tool for studying positronium
Adam Deller
Single-shot positron annihilation lifetime spectroscopy (SSPALS) is an extremely useful tool for experiments involving the positronium atom (Ps). I examine some of the methods that…
