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