Abstract The independent yield distribution of the Hg isotopes, measured for the reaction of 600 MeV 18O projectile with a nat.Pb target, is converted to 18O+208Pb system and is compared with an Hg-isotope distribution from the spallation reaction of 1 A GeV 208Pb on proton. The comparison shows the differences between the two distributions on the production cross sections, isotope-distribution widths as well as their shapes. A great increase of the neutron-deficient Hg isotope yield with increase of bombarding energies of protons from 600 MeV to 1 GeV is derived. This fact results in an experimental evidence for rapid increasing neutron yields with rising proton bombarding energy from 0.6 GeV to 1 GeV.
