Research Progress in the Exotic Nuclei Group

摘要

Digital decay spectroscopy of actinide isotopes at the gas lled separator SHANS Deacy spectroscopy of nuclei with Z>90 were performed using the 187Re+40Ar reaction with isotopically enriched 187Re targets.The 40Ar beam was accelerated to 188 MeV by the Sector-Focusing Cyclotron(SFC)of the Heavy Ion Research Facility in Lanzhou(HIRFL).The beam intensity on target,monitored via Faraday Cups upstream and downstream of the target chamber,was around 320 pnA on average during the entire experiment of 110 h.
