Comparisons of antiproton and proton cyclotron frequencies yield the ratio of inertial masses
M (p)/M (p)= 0.999 999 977±0.000 000 042. The fractional uncertainty of 4× 10− 8 is 1000 …

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 …

The process of radiative electron capture (REC) in relativistic collisions of high-Z ions with
low-Z gaseous and solid targets is studied experimentally and theoretically. The observed x …

Recent successes in confining antimatter in the form of positron and antiproton plasmas
have created new scientific and technological opportunities. Plasma techniques have been …

We propose a novel technique which uses laser-cooled negative osmium ions for
sympathetic cooling of antiprotons. Temperatures down to the sub-millikelvin range might be …

This article describes the capture of heavy negative particles (μ−, π−, K−,) by normal atoms,
ions and molecules to form exotic systems. Capture by even the hydrogen atom presents …

Abstract The classical-trajectory Monte Carlo method has been used to determine the cross
section for strip** of H− in collisions with p. The calculations were done for relative …

Radiative recombination of bare ions with electrons is discussed as a time-reversed
photoionization process in the nonrelativistic dipole approximation. Analytical expressions …

Up to more than one million antiprotons from a single LEAR spill have been captured in a
large Penning trap. Surprisingly, when the antiprotons are cooled to energies significantly …

The production of antihydrogen is examined in the light of recent experimental results on a
technique for the efficient accumulation, manipulation, and storage of positrons. From these …
