Gautschi-type and implicit-explicit integrators for constrained wave equations
R. Altmann, B. Dörich, C. Zimmer
This paper deals with the construction and analysis of two integrators for (semi-linear) second-order partial differential-algebraic equations of semi-explicit type. More precisely…
Efficient positronium production by stimulated decay from the level
M. Antonello, A. Belov, G. Bonomi +48
We investigate experimentally the possibility of enhancing the production of positronium atoms by driving the - and - transitions, overcoming the nat…
Rydberg-positronium velocity and self-ionization studies in 1T magnetic field and cryogenic environment
M. Antonello, A. Belov, G. Bonomi R. S. Brusa +43
We characterized the pulsed Rydberg-positronium production inside the AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) apparatus in view of antihydrogen formati…
Post-hatching parental care behaviour and hormonal status in a precocial bird
M. Boos, C. Zimmer, A. Carriere +2
In birds, the link between parental care behaviour and prolactin release during incubation persists after hatching in altricial birds, but has never been precisely studied during t…
A cryogenic tracking detector for antihydrogen detection in the AEgIS experiment
C. Amsler, M. Antonello, A. Belov +55
We present the commissioning of the Fast Annihilation Cryogenic Tracker detector (FACT), installed around the antihydrogen production trap inside the 1 T superconducting magnet of…
Measurement of antiproton annihilation on Cu, Ag and Au with emulsion films
S. Aghion, C. Amsler, A. Ariga +69
The characteristics of low energy antiproton annihilations on nuclei (e.g. hadronization and product multiplicities) are not well known, and Monte Carlo simulation packages that us…
