[en] The total cross sections of nuclear reactions in the energy range between several MeV and several tens of MeV have not been sufficiently studied at the present time. In many cases there are no experimental data. There is often a question of accuracy with which the cross sections can be calculated using theoretical models. At the same time, these types of nuclear constants are essential for the development of every nuclear technology. In the present work, an excitation function of nuclear reactions has been experimentally studied by the formation of long-lived radionuclides from the interaction of 47 MeV deuterons with zirconium of natural isotopic abundance. The experimental results are compared with theoretical calculations performed within the framework of a preequilibrium emission model and the evaporation of particles from a compound nucleus. Earlier an analogous study of the excitation function of proton-induced reactions was conducted
