Half-Lives of Argon-37, Argon-39, and Argon-42
The half-lives of three argon isotopes have been carefully determined, with the following results: Ar 37 , 35.1 ± 0.1 days; Ar 39 , 269 ± 3 years; Ar 42 , 32.9 ± 1.1 years. By combining the Ar 42 value with earlier data, a cross section of 0.5 ± 0.1 barn is calculated for the reaction, with thermal neutrons, Ar 41 (n,γ)Ar 42 .
