In recent years, there has been a wealth of new science involving low-energy antimatter (ie,
positrons and antiprotons) at energies ranging from 10 2 to less than 10-3 eV. Much of this …

The hydrogen atom continues to be a testbench for a wide variety of fundamental physical
measurements, whose scope has been expanded to the hydrogen-like atoms positronium …

Antimatter was first predicted in 1931, by Dirac. Work with high-energy antiparticles is now
commonplace, and anti-electrons are used regularly in the medical technique of positron …

Antihydrogen atoms with K or sub-K temperature are a powerful tool to precisely probe the
validity of fundamental physics laws and the design of highly sensitive experiments needs …

Atoms made of a particle and an antiparticle are unstable, usually surviving less than a
microsecond. Antihydrogen, made entirely of antiparticles, is believed to be stable, and it is …

Abstract PUMA, antiProton Unstable Matter Annihilation, is a nuclear-physics experiment at
CERN aiming at probing the surface properties of stable and rare isotopes by use of low …

Antihydrogen, a positron bound to an antiproton, is the simplest anti-atom. Its structure and
properties are expected to mirror those of the hydrogen atom. Prospects for precision …

The positron, the antiparticle of the electron, predicted by Dirac in 1931 and discovered by
Anderson in 1933, plays a key role in many scientific and everyday endeavours. Notably, the …

Positrons (ie, antielectrons) find use in a wide variety of applications, and antiprotons are
required for the formation and study of antihydrogen. Available sources of these antiparticles …

We report the application of evaporative cooling to clouds of trapped antiprotons, resulting in
plasmas with measured temperature as low as 9 K. We have modeled the evaporation …
