Three-charge-particle collwions between antiprotons (p) and muonic hydrogen atoms (Hµ) at low-energies — •Renat A. Sultanov — Odessa College, Department of Mathematics, 201 W. University Blvd., Odessa, Texas 79764, USA
A detailed few-body treatment is performed for two low-energy three-charge-particle reactions. The first reaction is between an antiproton p and a ground state muonic deuterium Dµ− - a bound state of a negative muon µ− and the deuterium nucleus D. The second reaction is between p and a muonic tritium Tµ−. In the first reaction additional final-state nuclear pD interaction inside the (pD) antiprotonic atom is taken into account and the effect of the strong pD nuclear forces on the reaction cross-sections and rates is computed. It was found that at low energy collisions, Ecoll ∼ 10−3−10−1eV, the influence of the strong interaction is significant, i.e. the reaction cross sections and rates are increased by ∼300%. In the second reaction the final state pT nuclear interaction has also been included and the effect was approximately estimated. Modified Faddeev-type equations have been applied to the three-body systems [1, 2].
