Abstract：
The average independent production cross sections of the radioactive Hg isotopes in the mass range of 180 to 209, produced in 600MeV-¹⁸O bombardment on (nat)Pb (thick target), were measured. The production mechanisms for the Hg-isotope products at different mass section were discussed by means of a comparison with the Hg-isotope distribution obtained in 600 MeV proton bombardment on ^natPb. The measlesment results were also compared with the Ir-isotope distribution observed from relativistic ¹⁹⁷Au projectile fragmentation reaction. The present experiment results showed that using intermediary-energy heavy ion beams bombarding neutron-rich heavy targets is a favourable reaction to produce neutron-rich heavy residues.
