Nuclear-Charge Screening in Positronium Formation from Helium Atoms
An analytical treatment of the electron screening effect within an active-electron model is given for positronium formation from helium atoms. A first-order distorted wave approximation with correct boundary conditions is applied to evaluate the transition amplitude. In the range of impact energy for which the introduced perturbative approach is valid, both the total and differential cross sect...

متن کاملHyperfine Splitting in Heavy Ions with the Nuclear Magnetization Distribution Determined from Experiments on Muonic Atoms
The hyperfine splitting in hydrogenlike 209Bi, 203Tl, and 205Tl is calculated with the nuclear magnetization determined from experimental data on the hyperfine splitting in the corresponding muonic atoms. The single-particle and configuration-mixing nuclear models are considered. The QED corrections are taken into account for both electronic and muonic atoms. The obtained results are compared w...
متن کاملCoherent muon–electron conversion in muonic atoms
Transition rates for coherent muon-electron conversion in muonic atoms, μN → eN , are computed for various types of muon number violating interactions. Attention is paid to relativistic atomic effects, Coulomb distortion, finite nuclear size, and nucleon distributions. Discrepancies with previously published results are pointed out and explained. Results are presented for several elements of cu...
متن کاملCascade in Muonic and Pionic Atoms with Z = 1
Recent theoretical and experimental studies of the exotic atoms with Z = 1 are reviewed. An interplay between the atomic internal and external degrees of freedom is essential for a good description of the atomic cascade. The perspective of ab initio cascade calculations is outlined.
