A simple method for the electrodeposition of elemental arsenic (As) on a metal backing from aqueous solutions has been developed.
The method was successfully applied to stable As (75As). Thin (2.5 mg cm−2) coherent, smooth layers of the metalloid on Ti foils (2.5 μm thickness) were obtained. Electrodeposits served as targets
for 75As(n,γ) 76As neutron capture experiments at Los Alamos Neutron Science Center (LANSCE). Respective 73As(n,γ) 74As experiments are planned for the near future, and 73As targets will be prepared in a similar fashion utilizing the new electrodeposition method. The preparation of an 73As (half-life 80.3 days) plating bath solution from proton irradiated germanium has been demonstrated. Germanium target irradiation
was performed at the Los Alamos Isotope Production Facility (IPF).
