Abstract

A new gas-filled recoil ion separator GARIS-II was on-line tested by using two 40Ar-induced fusion reactions of 169Tm(40Ar,4n)205Fr and 208Pb(40Ar,3n)245Fm, respectively. The products were collected to a focal plane with high efficiency of 47 ± 1 and 63 ± 9 % for 205Fr and 245Fm under low background condition.
