The enrichment of ^<76>As by means of the hot atom effect of neutron capture reaction has been carried out by using benzenearsonic acid as a target. Arsenites were carefully removed in advance from benzenearsonic acid. After irradiating for 2 hours in the pneumatic tube of atomic pile JRR-1 (thermal neutron flux is about 10^<11>n/cm^2・sec.), benzenearsonic acid was dissolved in 12 ml of 11 N hydrochloric acid. Resulting solution was then shaken with 10 ml of benzene and the recoiled arsenic was extracted into benzene layer. This layer was stripped with water, and ^<76>As was obtained in aqueous solution. The present enrichment method is advantageous in that radiochemically and chemically pure ^<76>As is obtained by comparatively simple and rapid procedures in a single oxidation state of trivalency in diluted hydrochloric acid solution . And it was found that the retention value of recoil fragments was about 15〜20% and about 80% of it was present in trivalent state.
