Abstract：
The neutron-rich target-like isotope ²³⁶Th was produced in ²³⁸U-2p multinucleon transfer reaction between a 60MeV/u ¹⁸O beam and nature ²³⁸U targets. The thorium activities were radiochemically separated from the mixture of uranium and reaction products. The isotope ²³⁶Th was identified by 642.2keV, 687.6keV and 229.6keV characteristic γ-rays. The production cross section of ²³⁶Th has been determined to be 250±50μb.
