[en] Recent results on the masses of the π^-, K^-, anti p, and Σ^-, as well as on the magnetic moments of the anti p and Σ^-, are presented. The strong hadron-nucleus interaction is discussed for π^-, K^-, and anti p. Especially, the influence of precision measurements of light pionic atoms on the understanding of the π^--nucleus s-wave interaction is pointed out. New measurements on deformed nuclei with pions are discussed in terms of the quadrupole deformation of the neutron distribution. The difficulties in understanding the K^--nucleus interaction are demonstrated. Recent measurements on light anti p atoms are reported. In particular the first observed isotope effect in anti p atoms (¹⁶O/¹⁸O) is discussed in terms of differences in the anti pn and anti pp interaction
