[en] The contribution of hadronic vacuum polarization to the energy levels of muonic atoms is reevaluated using an improved parametrization of the total cross section for e⁺e^- → hadrons. The numerical results can be simply related to the correction due to muonic vacuum polarization. (orig.)

[en] A polarization shift of the levels and a corresponding polarization potential has been found for muonic atoms with Zapprox.10--50, for which the Coulomb energy of the muon is on the order of or greater than the characteristic excitation energy of the nucleus

[en] Two projects of the experimental study of nuclear reactions between light nuclei (p, d, t, He, Li, Be) in the region of very low energies are presented. The first proposal deals with nuclear fusion reactions in charge-nonsymmetric muonic molecular complexes such as ^3,4He dμ, ^3,4He tμ, ^6,7Li pμ, ^6,7Li tμ. In the second one we consider a new approach to the measurement of nuclear reaction cross sections of light nuclei (p, d, t) in the range of 0.01-2 keV, using high intensity radially converging ion flow generated during linear implosion in plasma with the use of high power pulsed generator. The choice of experimental conditions has been made and lower limits of the measured values (fusion rates and cross sections) have been estimated. (author). 23 refs, 5 figs, 1 tab

[en] Experimental research is summarized on nuclear energy levels including pionic and muonic x rays. A list of publications is included

[en] The field of pionic and muonic atom research is reviewed with emphasis on papers contributed to the 8th International Conference on High Energy Physics and Nuclear Structure. (orig.)

[en] 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
