A gas-jet transport system for the SHE chemistry has been coupled to the gas-filled recoil ion separator GARIS at the RIKEN Linear Accelerator. The performance of the system was appraised using 
Fr and 
Fm produced in the 
Tm(
Ar,3
)Fr and 
Pb(Ar,3)Fm reactions, respectively. The 
particles of Fr and Fm separated with GARIS and transported by the gas-jet were identified with a rotating wheel system for spectrometry under desired low background condition. The high gas-jet efficiencies over 80% were independent of the beam intensities up to 2 particle 
A. A gas-jet coupled target system for the production of SHEs was also installed on the beam line of the RIKEN K70 AVF cyclotron. The gas-jet transport of 
No and 
Rf produced in the 
U(
Ne,5)No and 
Cm(
O,5)Rf reactions, respectively, was conducted for the future chemical studies of 
Sg via the Cm(Ne, 5)Sg reaction.

The extraction behavior of trivalent actinides (Am, Cm, Cf, Es, and Fm) into di(2-ethylhexyl)phosphoric acid, HDEHP, in benzene from HNO
was studied together with lanthanides. The extraction constants, 
values, of lanthanides, Am, Cm, Cf, and Es were determined by a batch method using stable lanthanide isotopes and radiotracers of 
Am, 
Cm, 
Cf, and 
Es, respectively, while that of Fm was measured with 
Fm which was produced in the U(
O,4n) reaction and was on-line supplied by a gas-jet method at the AVF cyclotron of RCNP, Osaka University. The values were determined by the slope analysis for the variation of the distribution ratio as a function of the concentration of HDEHP. We found that the of Fm is smaller than that of Dy in spite of the similar ionic radii while those of other actinides are almost the same as those of each lanthanide with a similar ionic radius.
