摘要
The distribution of nuclei produced in the^(40)Ar+^(232)Th reaction has been studied at the gas-filled recoil separator(SHANS2)at the China Accelerator Facility for Superheavy Elements(CAFE2).The bombardment was carried out at a beam energy of 205 MeV with the detection system installed at the focal plane.Forty-four isotopes heavier than 208Pb were observed.These isotopes were identified as the transfer reaction(or target-like)products,and their relative cross-sections were extracted.Based on the mass distribution of these products,we exclude the possibility that they were produced by fusion-fission reactions;thus,they may originate from quasi-fission of the^(40)Ar+^(232)Th reaction.
