The coherent inelastic processes of the type a b, which may take place in the interaction of hadrons and quanta with nuclei at very high energies (the nucleus remains the same), are theoretically investigated. For taking into account the influence of the nucleus matter, the optical model, based on the concept of refraction index, is used . Analytical formulas for the effective cross section coh a b are obtained, taking into account that at ultrarelativistic energies the main contribution into coh a b is provided by very small transferred momenta in the vicinity of the minimum longitudinal momentum transferred to the nucleus. It is shown that the cross section coh a b may be expressed through the "forward" amplitudes of inelastic scattering fa N b N and elastic scattering fa N a N , fb N b N on a separate nucleon, and it depends on the ratios La R and Lb R, where La, Lb are the respective mean free paths in the nucleus matter for the particles a, b and R is the nuclear radius.
