Abstract：
The progress and the on-line experimental results of isotope separator on-line in Lanzhou(ISOLAN) by using the low and the medium energy beams are described. The resolving power of ISOLAN is obtained to be 500\_700 for Xe by using FEBIAD ion source. The off-line overall efficiency is 3.1% for Krypton and 4.5% for Xenon. The on-line overall efficiency is 1.5%—2.0% for ¹⁰⁴In, ¹⁰⁴Ag and ¹⁰⁴Gd,and 5% for ¹⁹⁹Hg. The isotopes of Hg,At and Rn produced in the bombardment of natural lead targets with ¹⁸O beam at 30MeV/u were successfully separated by ISOLAN. The highest energy of 1.234 MeV of γ-ray originated from the decay of ²⁰⁸Hg with a production cross-section of 5μb was observed.
