Fragmentation of hadrons on nuclei and intranuclear absorption

Hadron absorption coefficients in the nuclear matter are measured for incoherent channels of multiple production by relative attenuation of the 'beam' of secondary leading particles, emerging within a fixed interval of momenta and emission angles from various nuclei as compared with pp-interaction. The rearrangement of hadron quark structure in substantially inelastic 'soft' processes, if there is any, entails no significant disturbances at a level of real particle properties. In this energy region incoherent proton fragmentation on nuclei proceeds generally through a bound baryonic state (of the type of an isobar or difractive cluster) being absorbed in the nuclear matter like an ordinary proton and decaying into hadrons outside the nucleus
