First observation of two hyperfine transitions in antiprotonic He-3

S. Friedreich, D. Barna, F. Caspers +11

We report on the first experimental results for microwave spectroscopy of the hyperfine structure of antiprotonic He-3. Due to the helium nuclear spin, antiprotonic He-3 has a more…

Universal Four-Boson States in Ultracold Molecular Gases: Resonant Effects in Dimer-Dimer Collisions

J. P. D'Incao, J. von Stecher, Chris H. Greene

We study the manifestations of universal four-body physics in ultracold dimer-dimer collisions. We show that resonant features associated with three-body Efimov physics and dimer-d…

Line shape of the muH(3p - 1s) hyperfine transitions

D. S. Covita, D. F. Anagnostopoulos, H. Gorke +13

The (3p - 1s) X-ray transition to the muonic hydrogen ground state was measured with a high resolution crystal spectrometer. A Doppler effect broadening of the X-ray line was estab…

Precision measurement of the branching fractions of the 4P3/2 decay of Ca II

R. Gerritsma, G. Kirchmair, F. Zaehringer +3

We perform precision measurements of the branching ratios of the 4P3/2 level decay of a single 40Ca+ ion suspended in a linear Paul trap. High precision is achieved by a novel tech…

Improved Study of the Antiprotonic Helium Hyperfine Structure

T. Pask, D. Barna, A. Dax +10

We report the initial results from a systematic study of the hyperfine (HF) structure of antiprotonic helium (n,l) = (37,~35) carried out at the Antiproton Decelerator (AD) at CERN…

Highly charged ion X-rays from Electron-Cyclotron Resonance Ion Sources

Paul Indelicato, S. Boucard, D. S. Covita +13

Radiation from the highly-charged ions contained in the plasma of Electron-Cyclotron Resonance Ion Sources constitutes a very bright source of X-rays. Because the ions have a relat…
