Fine structure in the α decay of high-spin isomers in 155Lu(25/2−) and 156Hf (8+) has been studied for the first time using αγ -coincidence analysis. Three new α decays from 155Lu(25/2−) and two from 156Hf (8+) have been identified, populating seniority s > 1 states in the N = 82 nuclei 151Tm and 152Yb, respectively. The reduced hindrance factors of the α decays support the previous configuration assignments of the populated states. This is the first observation of states with excitation energy greater than 1.5 MeV being populated following α decay in nuclei outside of the 208Pb region.

Van; Beeke, O.; Dodson, B.; Scholey, Catherine; O’Donell, D.; Jakobsson, Ulrika; Grahn, Tuomas; Greenlees, Paul; Jones, Peter; Julin, Rauno; Khan, S.; Leino, Matti; Leppänen, Ari-Pekka; Eeckhaudt, Sarah; Mäntyniemi, K.; Pakarinen, Janne; Peura, Pauli; Rahkila, Panu; Sarén, Jan; Sorri, Juha; Uusitalo, Juha; Venhart, M. (American Physical Society, 2018)

Excited states above the 17+ isomeric state in the proton-rich nucleus 152Tm were established by employing the recoil-isomer tagging technique. Data were collected using the JUROGAM gamma-ray array and the GREAT spectrometer ...
Exploring the boundaries of the nuclear landscape : α-decay properties of 211Pa

Auranen, K.; Uusitalo, J.; Badran, H.; Grahn, T.; Greenlees, P. T.; Herzáň, A.; Jakobsson, U.; Julin, R.; Juutinen, S.; Konki, J.; Leino, M.; Leppänen, A.-P.; O'Neill, G.; Pakarinen, J.; Papadakis, P.; Partanen, J.; Peura, P.; Rahkila, P.; Ruotsalainen, P.; Sandzelius, M.; Sarén, J.; Scholey, C.; Sinclair, L.; Sorri, J.; Stolze, S.; Voss, A. (American Physical Society (APS), 2020)

Employing the recoil ion transport unit (RITU) and a fusion-evaporation reaction, the α decay of 211Pa has been identified via the implantation-decay correlation technique through observation of chains up to four consecutive ...

(American Physical Society, 2018)

Using fusion-evaporation reactions, a gas-filled recoil separator, recoil-gating technique and recoil-isomer decay tagging technique we have extended the level scheme of 203 At ( N = 118 ) significantly. We have ...
Isomeric 13/2+ state in 201Fr

Auranen, K.; Jakobsson, U.; Badran, H.; Grahn, T.; Greenlees, P. T.; Herzán, A.; Julin, R.; Juutinen, S.; Konki, J.; Leino, M.; Leppänen, A.-P.; O'Neill, G.; Pakarinen, J.; Papadakis, P.; Partanen, J.; Rahkila, P.; Ruotsalainen, P.; Sandzelius, M.; Sarén, J.; Scholey, C.; Sinclair, L.; Sorri, J.; Stolze, S.; Uusitalo, J.; Voss, A. (American Physical Society, 2020)

We have identified an isomeric state in 201Fr for which we propose a spin and parity of 13/2 +, and interpret it as arising from the π(i13/2 ) configuration. A half-life of 720(40) ns was measured, corresponding to B(M2) ...
