Inelasticity in hadron-nucleus collisions from emulsion chamber studies - art. no. 014025.

The inelasticity of hadron-carbon nucleus collisions in the energy region e xceeding 100 TeV is estimated from the carbon-emulsion chamber data at Pami rs to be [K-C] = 0.65 +/- 0.08. When combined with the recently presented d ata on hadron-lead nucleus collisions taken at the same energy range it res ults in the K similar to A(0.086) mass number dependence of inelasticity. T he evaluated partial inelasticity for secondary (nu > 1) interactions, K-nu >1 similar or equal to 0.2, suggests that the second and higher interaction s of the excited hadron inside the nucleus proceed with only slight energy losses.
