Abstract: 
The exclusive production of pi and eta mesons in hadron-nucleus reactions is studied in the framework of the impulse approximation in momentum space using relativistic nucleon spinors. A comparison with the data on pion production for 800 and 489 MeV protons on C-12, O-16 and B-10 shows the relativistic effects to be predominant for reactions leading to the ground state as well as excited states of the residual nuclei. The exclusive production of low energy eta mesons in pion-nucleus interactions is investigated with particular emphasis on the N(1535) self-energy in the medium. Furthermore, first calculations for the reaction C-12(p, eta)N-13(g.s.) are presented for 0.8 and 1.0 GeV laboratory. The sensitivity of the calculated cross section to different limits for the NN eta coupling constant and the role of one-step and two-step processes is studied.
