| Research Abstract |
Solvent extraction experiments were performed by a batch method with all lanthanide elements as well as long-lived actinide elements, Am, Cm, and Cf. Rapid and automatic chemistry apparatus connected with nuclear reaction chamber at accelerator setup was developed and tested, and using the apparatus, we performed solvent extraction with heavy actinide elements, Bk Es, Fm, and Md. From these data, the extraction properties were able to be systematically and widely discussed through all lanthanide elements and many actinide elements. As a result, stronger influence of f electrons on the chemical bonding is suggested in actinide elements than in lanthanide.
