Abstract

Chromium-51 decays through electron capture, the probability of which is perturbed by its electronic state. We have precisely measured the decay constants (λ) of ⁵¹Cr with metal (Cr⁰), oxide (Cr³⁺), and chromate (Cr⁶⁺) to investigate the effects of chemical states on the decay constants of ⁵¹Cr. The value of (Formula presented.) was determined to be (6.4 ± 3.7) × 10⁻⁴, whereas the difference less than 1.4 × 10⁻⁴ was observed for (Formula presented.).
