Chemical effects on nuclear decay of ${}^{235}$U isomer in the uranyl form

Y. Shigekawa, K. Sawamura, S. Hashiba +8

The nucleus of uranium-235 (${}^{235}$U) possesses an exceptionally low-energy isomeric state, ${}^{235m}$U. Unlike most radioactive nuclides, whose nuclear-decay half-lives are consta…
