The process of hadron‐nucleus interaction associated with the knockout of considerable number of nucleons from the nucleus is investigated in the framework of intra‐nuclei cascade model. It is shown that final states of target nucleus corresponding to the knockout of all possible numbers of nucleons form a continuous spectrum. Obtained results are discussed in connection with the problem of possible existence of multi‐nucleon clusters in the nuclei. It is shown that intra‐nuclear cascade model allows great occurrences of exited nuclear states corresponding to the knockout of &agr;‐clusters in hadron‐nucleus scattering process without the assumption of their existence in the nucleus.
