Abstract

A technology to utilize radioisotopes of Nb and Ta was developed for chemical studies of element 105, Db, by coupling a gas-jet transport system to the RIKEN gas-filled recoil ion separator (GARIS). ⁸⁸Nb and ¹⁷⁰Ta were generated via the ^natGe(¹⁹F, xn)⁸⁸Nb and ^natGd(¹⁹F, xn)¹⁷⁰Ta reactions, respectively. They were separated by GARIS and extracted by the gas-jet method to a chemistry laboratory under the almost same experimental conditions for ²⁶²Db produced in the ²⁴⁸Cm(¹⁹F, 5n)²⁶²Db reaction. Yields of ⁸⁸Nb and ¹⁷⁰Ta at the chemistry laboratory were optimized by changing the setting parameters of the GARIS gas-jet system, such as magnetic field of GARIS, energy degrader and shutter for recoil ions, and volume of the recoil transfer chamber.
