Much progress in the theory of positron scattering on atoms has been made in the ten years
since the review of Surko et al (2005 J. Phys. B: At. Mol. Opt. Phys. 38 R57). We review this …

Utilizing the two-center convergent close-coupling method, we find a several order of
magnitude enhancement in the formation of antihydrogen via antiproton scattering with …

The two-center convergent close-coupling method is used to calculate antihydrogen (H¯)
formation via positronium (Ps) scattering on antiprotons (p¯) at near threshold energies. For …

Abstract Tests of the Weak Equivalence Principle (WEP) probe the foundations of physics.
Ever since Galileo in the early 1600s, WEP tests have attracted some of the best …

The interaction of antiprotons with low-energy positronium atoms is a fundamental three-
body problem whose significance is its utility for formation of antihydrogen. Particular …

The creation of cold antihydrogen atoms by the controlled combination of positrons and
antiprotons has opened up a new window on fundamental physics. More recently …

We investigate the consequences of unexpectedly large elastic cross sections for the
scattering of low-energy antiprotons from n≤ 3 positronium (Ps) on the experimental …

For over forty years it has been possible to investigate the interactions of low energy
positrons using well-defined beams colliding with atoms, molecules and surfaces. The ability …

We present a method for generating cold neutral atoms via charge exchange reactions
between trapped ions and Rydberg positronium. The high charge exchange reaction cross …

The convergent close-coupling method is used to obtain cross sections for antihydrogen
formation in low-energy antiproton collisions with positronium (Ps) atoms in specified initial …
