Research output › peer-review

Abstract

⁸³As and ⁸⁴As fission products are separated at short time intervals from ²³⁵U irradiated with thermal neutrons and are studied by separating and measuring the activities of their bromine grand-daughters. ⁸³As has a 14·1 ± 1·1 sec half-life and decays predominantly to 70 sec ^83mSe; ⁸⁴As has a 5·8±0·5 sec half-life. The fractional cumulative yields for thermal fission are 0·80±0·08 for ⁸³As and 0·17±0·02 for ⁸⁴As. The nuclear charge distribution in this mass region, analysed in terms of Wahl's empirical Z_P function, shows a fine-structure effect at mass 84.
