Studies on gaseous electrodeposition of recoiled nuclides from thorium series

A point source of²¹²Pb was prepared from²²⁸Th source by the gaseous electrodeposition method. A conical tube was placed between the electrodes and it served as a metallic shade to make lines of electric force converge to the collector cathode. The source was utilized to measure the rate of²⁰⁸Tl emission and the rate of electrodeposition in various gaseous matrices. The mechanism of the mass transfer of recoiled species from the source to the collector was also revealed predominantly to be migration of the recoiled ions.
