We studied the stability of a system consisting of a positron (e+) and two lithium anions,[Li−;
e+; Li−], using first-principles quantum Monte Carlo calculations combined with the multi …

The novel proposal of the Muon Catalyzed Fusion (MCF) concept is brought to light
employing recent results on its relevant cross sections. In 1993, Kino et al. proposed an …

Positron binding to neutral atoms, which to this day have not been detected experimentally,
is thought to be rather weak. According to a few reliable nonrelativistic calculations reported …

In this paper we present the first pilot calculation of the elastic and inelastic cross sections for
the 5-body scattering of antihydrogen ions with positronium atoms. These cross sections …

S-wave Feshbach resonance states belonging to dipole series in positronic alkali atoms (e+
Li, e+ Na, e+ K, e+ Rb and e+ Cs) are studied by coupled-channel calculations within a …

We report a theoretical calculation of the relativistic corrections to the binding energy of
positronic alkali-metal atoms. The ground state for the positronic alkali-metal atom is a …

We report a four-body variational calculation of a hydrogen-like atom consisting of an
excited muonic molecule consisting of d, t, and μ, and a ground state electron. Due to the …

In this paper, we present a complex-coordinate rotation calculation for high-lying S-wave
resonances in positron-helium scattering. Highly correlated Hylleraas wave functions …

We analyze two shallow resonance states below the antiproton hydrogen dissociation
threshold with a non-adiabatic three-body calculation. Rearrangement correlation between …

We report a theoretical study of antihydrogen-hydrogen molecular resonance states
consisting of a positron, an antiproton, an electron and a proton. The four particles strongly …
