Investigation of the mechanisms of spallation reactions

The knowledge of the mechanism of spallation reactions induced by protons and pions on various atomic nuclei is crucial for understanding of many physical phenomena as, e.g., the modification of nuclear content of cosmic rays during their propagation through the interstellar space, evolution of heavy stars, etc. It is also crucial in many technical applications as, e.g., accelerator driven subcritical reactors as well as in radioactive waste transmutation, construction and application of spallation neutron-sources. Thus, the knowledge of spallation cross sections is indispensable for understanding of these physical phenomena and for technical applications. Since some of the important targets and/or product nuclei are unstable it is necessary in such a case to rely on theoretically estimated spallation cross sections
