Abstract

The half-lives of three argon isotopes have been carefully determined, with the following results: Ar³⁷, 35.1 ± 0.1 days; Ar³⁹ 269 ± 3 years; Ar⁴², 32.9 ± 1.1 years. By combining the Ar⁴² value with earlier data, a cross section of 0.5 ± 0.1 barn is calculated for the reaction, with thermal neutrons, Ar⁴¹(n,γ)Ar⁴².
