Experimental and theoretical developments of the last decade in the study of exotic atoms and some related low-energy reactions are reviewed, in order to provide information on the in-medium hadron-nucleon t matrix over a wide range of densities up to central nuclear densities. In particular, we review pionic deeply bound atomic states and related evidence for partial restoration of chiral symmetry in dense nuclear matter. The case for relatively narrow deeply bound atomic states for antikaons and antiprotons is made, based on the physics of strong nuclear absorption. Recent experimental suggestions for signals of antikaon-nuclear deeply bound states are reviewed, and dynamical models for calculating binding energies, widths and densities of antikaon nuclear states are discussed. Specific features of low-energy in-medium interactions of kaons, antiprotons and of Sigma hyperons are discussed, and suggestions to study experimentally Cascade atoms are reviewed.Comment: 86 pages, 44 figures, slight revisions, references added, Physics Reports (in press

“…For the scattering of spin zero mesons the Kemmer-Duffin-Petiau (KDP) equation [17][18][19] rather than the Dirac equation is used. This KDP-RIA approach has been used to obtain optical potentials for both kaon-nucleus and pion-nucleus elastic scatter-ing [2,[20][21][22]. The construction of the Lorentz scalar and vector optical potentials parallels that of the usual RIA.…”

Pion-nucleus elastic scattering at energies above the ∆(1232) resonance is studied using both π + and π − beams on 12 C, 40 Ca, 90 Zr, and 208 Pb. The present data provide an opportunity to study the interaction of pions with nuclei at energies where second-order corrections to impulse approximation calculations should be small. The results are compared with other data sets at similar energies, and with four different first-order impulse approximation calculations. Significant disagreement exists between the calculations and the data from this experiment. 25.80.Dj, Typeset using REVT E X 2

“…The data at 715 MeV/c and 800 MeV/c are from Refs. [26] and [27] The thick curves represent full-folding results; the dotted and thinner solid curves correspond to on-and off-shell tρ results, respectively. The dashed curves represent full-folding results with the separable strength of the elemental K + N potential suppressed.…”

We investigate K + -nucleus elastic scattering at intermediate energies within a microscopic optical model approach. To this effect we use the current K + -nucleon (KN) phase shifts from the Center for Nuclear Studies of the George Washington University as primary input. First, the KN phase shifts are used to generate Gel'fand-Levitan-Marchenko real and local inversion potentials. Secondly, these potentials are supplemented with a short range complex separable term in such a way that the corresponding unitary and non-unitary KN S matrices are exactly reproduced. These KN potentials allow to calculate all needed on-and off-shell contributions of the t matrix, the driving effective interaction in the full-folding K + -nucleus optical model potentials reported here. Elastic scattering of positive kaons from 6 Li, 12 C, 28 Si and 40 Ca are studied at beam momenta in the range 400-1000 MeV/c, leading to a fair description of most differential and total cross section data. To complete the analysis the full-folding model, three kinds of simpler tρ calculations are considered and results discussed. We conclude that conventional medium effects, in conjunction with a proper representation of the basic KN interaction are essential for the description of K + -nucleus phenomena.
