Lifetime of the singly charged $^{229}$ Th nuclear isomer

Y. Shigekawa, A. Yamaguchi, K. Tokoi +6

The nucleus of thorium-229 ( $^{229}$ Th) has an exceptionally low-energy isomeric state ( $^{229 m}$ Th). Because its excitation energy is close to the energy levels of valenc…

Demonstration of inkjet-printed targets for activation cross-section measurements: deuteron-induced reactions on strontium up to 24 MeV

Akihiro Nambu, Masayuki Aikawa, Yudai Shigekawa +4

Excitation functions for the $^{na t}$ Sr( $d, x$ ) reactions producing $^{86 m, g}$ Y, $^{87 m, g}$ Y, and $^{88}$ Y were measured up to 24-MeV deuteron energy using the stacked-foil techniqu…

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, $^{235 m}$ U. Unlike most radioactive nuclides, whose nuclear-decay half-lives are consta…
