Using a fusion-evaporation reaction and a gas-filled recoil separator, an isomeric state [T12=83(8)μs] with a most likely spin and parity of 132+ has been identified in Th211. The isomeric state is mainly depopulated via a hindered internal M2 transition [B(M2)=0.0025(5) W.u.], but also a weak α-decay branch of 4(3)% was observed. The present observations fit well to the systematic pattern set by the previously identified states of the same spin and parity in this region of the nuclear chart.

P.; Antalic, S.; Andel, B.; Ackermann, D.; Heinz, S.; Hofmann, S.; Khuyagbaatar, J.; Kindler, B.; Kojouharov, I.; Kuusiniemi, P.; Leino, M.; Lommel, B.; Mann, R.; Nishio, K.; Popeko, A. G.; Streicher, B.; Sulignano, B.; Uusitalo, J.; Venhart, M.; Yeremin, A. V. (American Physical Society (APS), 2022)The decay of excited states in 255No was investigated by applying the evaporation-residue–conversion-electron correlation technique. Two new isomeric states were observed in 255No together with the previously known one. ... -
Isomeric States in the Rapid Neutron Capture Process
Winter, Miikka (2024)The rapid neutron capture process, the r-process, is responsible for creating around a half of the nuclei above A ≈ 60. The r-process nucleosynthesis is simulated with a nuclear reaction network that evolves the system ... -
