Muon transfer from excited states of hydrogen and deuterium to nitrogen, neon, and argon

Abstract

Muon transfer from excited p* and d* atoms to the three gases nitrogen, neon, and argon is studied. Variations of the experimental conditions such as pressure and relative concentrations on the fractions ␣ pZ and ␣ dZ of excited state events in prompt muonic x rays are analyzed. The differences between excited-state transfer from p* and d* to N 2 , Ne, and Ar are discussed. For these elements, capture ratios A(H 2 ,Z) and A(D 2 ,Z) are given, from which an indirect value A(H 2 ,D 2 ) is deduced.

Coordinate-space Faddeev-Hahn-type approach to three-body charge-transfer reactions involving exotic particles

“…If one can identify the basic dynamical ingredients necessary for a satisfactory description of these processes involving a small number of particles, such a study will help us to formulate models in more complex situations. On the experimental side, the present study involving muon and positron transfer is of current interest in the muon-catalyzed fusion cycle [1][2][3][4][5][6] and in the formation and study of the antihydrogen atom [7,8].…”

“…Consequently, there has been considerable recent experimental interest in the study of the muon-transfer reaction in the collision of the muonic hydrogen by heavier nuclei, e.g. carbon (C 6+ ), oxygen (O 8+ ), neon (Ne 10+ ), argon (Ar 18+ ) [2][3][4][5][6] etc. On the theoretical side, these three-body charge transfer reactions involving a heavy transferred particle like muon and a strong Coulomb interaction in the final state involving nuclei, such as carbon and oxygen, continue to be challanging problems calling for new investigations.…”

Using the Emission of Muonic X-rays as a Spectroscopic Tool for the Investigation of the Local Chemistry of Elements

“…While the effect of the muonic-transfer on the emitted spectra in all H-containing materials cannot be excluded, the absence of differences in CaH 2 and CaD 2 help argue that the extent of this contribution should be marginal. Furthermore, muon transfer is less likely to affect heavier elements, as suggested by the systematic decrease in the muon transfer when comparing H to D [ 40 ]. It is therefore reasonable to conclude that the materials-dependent modulation of intensity of emitted X-rays, which we highlighted in µ-XES spectra, is mainly affected by the local electronic-structure of the material.…”
