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.).
