Available in PDF, EPUB and Kindle. Book excerpt: Topological cross sections [delta]{sub coh}{sup (n)} (n = 1,3,5 and 7) of coherent diffractive dissociation of 400 Gev/c protons on nuclei of photoemulsion elements have been measured. Topological cross sections increase in the energy range from 20 to 400 Gev/c. This growth is the most noticeable for multiprong topologies. The total cross section of diffractive coherent production also increases from 8 to 25 mb/nucleus in this energy range. The increasing of the average multiplicity of charged particles in reaction of coherent proton dissociates is consistent with the logarithmic law n{sub coh} = (90.25 ± 0.05) inp. + (1.3 ± 0.25).
