Abstract: The inelasticity distribution of hadron-lead collisions in the energy region exceeding 10(14) cV is estimated on the basis of 66 events, induced by cosmic ray hadrons and detected at high mountain altitudes at Pamir (4300 m, 595 g/cm(2)). The distribution of the best fitting is approximated as g(K)dK=[alpha(1-K)(m1-1) + beta Km2-1]dK, where m(1) = 0.5, m(2) = 1.125. alpha = 0.26, beta = 0.55, giving [K] = 0.60. The errors of the parameters are discussed in the text. The distribution is compared with those which are based on theoretical models.
