Cascade 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.
متن کاملLamb Shift in Muonic Helium Ion
The Lamb shift (2P1/2 − 2S1/2) in the muonic helium ion (μ 2He) is calculated with the account of contributions of orders α3, α4, α5 and α6. Special attention is given to corrections of the electron vacuum polarization, the nuclear structure and recoil effects. The obtained numerical value of the Lamb shift 1381.716 meV can be considered as a reliable estimate for the comparison with experiment...
متن کاملHyperfine Structure of S-states in Muonic Helium Ion
Corrections of orders α5 and α6 are calculated in the hyperfine splittings of 1S and 2S energy levels in the ion of muonic helium. The electron vacuum polarization effects, the nuclear structure corrections and recoil corrections are taken into account. The obtained numerical values of the hyperfine splittings -1334.56 meV (1S state), -166.62 meV (2S state) can be considered as a reliable estim...
متن کاملDetermination of Strong-Interaction Widths and Shifts of Pionic X-Rays with a Crystal Spectrometer*
upon one must (apart from the discretization) expect errors of 15-20% in the excitation spectrum; or one uses large-amplitude collective theories like ATDHF, wherein one describes just one energy moment out of a broad spectrum20 with no known relationship to the experimental peak energy. On the other hand, for heavier nuclei the monopole resonance is expected to be narrower, and there those lar...
متن کاملGround State Hyperfine Structure of Muonic Helium Atom
The muonic helium atom (μe2He) represents the simple three-body atomic system. The interaction between magnetic moments of the muon and electron leads to the hyperfine structure (HFS) of the energy levels. The investigation of the energy spectrum of this atom is important for the check of quantum electrodynamics for three-particle bound state. The ground state hyperfine splitting was measured m...
