Abstract：
Sources of ²³⁷Th has been prepared via a multinucleon transfer reaction by 60MeV/u ¹⁸O ions bombardment of natural uranium followed by radiochemical separation.The isotope ²³⁷Th has been identified.The half-life of ²³⁷Th was determined to be (4.69±0.60)min.Not only the new value is in agreement with the earlier one of (5.0±0.9)min obtained in our previous work,but also its experimental precision was improved.
