Single-color two-photon spectroscopy of Rydberg states in electric fields
T. E. Wall, D. B. Cassidy, S. D. Hogan
Rydberg states of atomic helium with principal quantum numbers ranging from n=20 to n=100 have been prepared by non-resonance-enhanced single-color two-photon excitation from the m…
Prospects for studies of the free fall and gravitational quantum states of antimatter
Gabriel Dufour, David B. Cassidy, Paolo Crivelli +6
Different experiments are ongoing to measure the effect of gravity on cold neutral antimatter atoms such as positronium, muonium and antihydrogen. Among those, the project GBAR in…
Preparation of an ultra-cold sample of ammonia molecules for precision measurements
Marina Quintero-Pérez, Thomas E. Wall, Steven Hoekstra +1
We present experiments in which an ultra-cold sample of ammonia molecules is released from an electrostatic trap and recaptured after a variable time. It is shown that, by performi…
