In the last few years transition energies in pionic and kaonic atoms have been measured with an unprecedented precision [1]. The spectroscopy of hadronic hydrogen allows to study the strong interaction at low energies [2] by measuring the energy and width of the ground level with a precision of few meV. The light hadronic atoms can additionally be used to define new low-energy X-ray standards and to evaluate the pion mass using high accuracy X-ray spectroscopy. Paper is devoted to studying spectra for hadronic (kaonic and pionic) atoms and some superheavy isotopes. Ab initio QED approach [3] with an accurate account of relativistic, nuclear, radiative effects is used in calculating spectra of the hadronic (pion, kaon) atoms. One of the main purposes is establishment a quantitative link between quality of nucleus structure modeling and accuracy of calculating energy and spectral properties of systems. The wave functions zeroth basis is found from the Klein-Gordon or Dirac equation. The potential includes the SCF ab initio potential, the electric and polarization potentials of a nucleus (the RMF, Fermi and Gauss models for a charge distribution in a nucleus are considered). For low orbits there are the important effects due to the strong hadron-nuclear interaction. The energy shift is connected with a length of the hadron-nuclear scattering. For superheavy isotopes (ions) the correlation corrections of high orders are accounted for within the Green function method. The Lamb shift polarization part- in the Uhling-Serber approximation and the self-energy part – within the Green functions method. We present the data on: 1).energy levels for superheavy isotopes Z=113,114; 2). Shifts and widths of transitions (2p-1s,3d-2p, 4f-3d etc) in some pionic and kaonic atoms (H, He, N, W, U). The calculated X-ray transitions spectrum for kaonic He and estimate of 2p level shift due to the strong K-N interaction 1.57 eV are in the reasonable agreement with experimental data (cited shift 1.9eV) by Okada et al (2008; E570; КЕК 12GeV, RIKEN Nishina Centre, JAPAN) and differ (about order) of other experimental data by Wiegand-Pehl (1971), Batty et al (1979), Baird et al (1983).
