Query: Inelaticity in hadron-nucleus collisions from emulsion chamber studies   The inelasticity of hadron-carbon nucleus collisions in the energy region
exceeding 100 TeV is estimated from the carbon-emulsion chamber data at Pamirs
to be $<K_C> = 0.65\pm 0.08$. When combined with the recently presented data on
hadron-lead nucleus collisions taken at the same energy range it results in the
$K\sim A^{0.086}$ mass number dependence of inelasticity. The evaluated partial
inelasticity for secondary ($\nu > 1$) interactions, $K_{\nu >1} \simeq 0.2$,
suggests that the second and higher interactions of the excited hadron inside
the nucleus proceed with only slight energy losses.
