/ Zimba, G L (Jyvaskyla U.) ; Ruotsalainen, P (Jyvaskyla U.) ; De Gregorio, G (Rome III U. ; INFN, Naples) ; de Angelis, G (INFN, Legnaro) ; Sarén, J (Jyvaskyla U.) ; Uusitalo, J (Jyvaskyla U.) ; Auranen, K (Jyvaskyla U.) ; Briscoe, A D (Jyvaskyla U.) ; Ge, Z (Jyvaskyla U.) ; Grahn, T (Jyvaskyla U.) et al.
Excited states in the Kr70 and Br70 nuclei were populated via the Ca40(S32,2n)Kr70 and Ca40(S32,pn)Br70 fusion-evaporation reactions at the Accelerator Laboratory of the University of Jyväskylä. The 2+⟶0+ and 4+⟶2+ transitions in Kr70 have been found to be 881(1) keV and (tentatively) 1037(2) keV, respectively. [...]

/ Louko, J (Jyvaskyla U.) ; Auranen, K (Jyvaskyla U.) ; Uusitalo, J (Jyvaskyla U.) ; Briscoe, A D (Jyvaskyla U.) ; Grahn, T (Jyvaskyla U.) ; Greenlees, P T (Jyvaskyla U.) ; Illana, A (Jyvaskyla U.) ; Joukainen, H (Jyvaskyla U.) ; Julin, R (Jyvaskyla U.) ; Jutila, H (Jyvaskyla U.) et al.
The first in-beam γ-ray spectroscopic study of the neutron-deficient actinium isotopes Ac211,213 has been carried out at the Accelerator Laboratory of the University of Jyväskylä using a highly selective recoil-decay tagging method with the jurogam 3 germanium-detector array and MARA separator. The nuclei of interest were produced using the Lu175(Ar40,4n)Ac211 and Hf180(Cl37,4n)Ac213 fusion-evaporation reactions. [...]

Direct measurement of three different deformations near the ground state in an atomic nucleus
/ Montes Plaza, Adrian (Liverpool U. ; Jyvaskyla U.) ; Pakarinen, Janne (Jyvaskyla U.) ; Papadakis, Philippos (Daresbury) ; Herzberg, Rolf-Dietmar (Liverpool U.) ; Julin, Rauno (Jyvaskyla U.) ; Rodríguez, Tomás R (Madrid U.) ; Briscoe, Andrew D (Jyvaskyla U. ; Liverpool U.) ; Illana, Andrés (Jyvaskyla U. ; Madrid U.) ; Ojala, Joonas (Jyvaskyla U.) ; Ruotsalainen, Panu (Jyvaskyla U.) et al.
Atomic nuclei serve as prime laboratories for investigations of complex quantum phenomena, where minor nucleon rearrangements cause significant structural changes. $^{190}$Pb is the heaviest known neutron-deficient Pb isotope that can exhibit three distinct shapes: prolate, oblate, and spherical, with nearly degenerate excitation energies.

Population of a low-spin positive-parity band from high-spin intruder states in $^{177}$Au: The two-state mixing effect
/ Venhart, M (Bratislava, Inst. Phys.) ; Balogh, M (Bratislava, Inst. Phys.) ; Herzáň, A (Bratislava, Inst.

The extremely neutron-deficient isotopes $^{177,179}$Au were studied by means of in-beam γ -ray spectroscopy. Specific tagging techniques, α -decay tagging in $^{177}$Au and isomer tagging in $^{179}$Au, were used for these studies. [...]

Isomeric 13/2$^+$ state in $^{201}$Fr
/ Auranen, K (Jyvaskyla U.) ; Jakobsson, U (Jyvaskyla U.) ; Badran, H (Jyvaskyla U.) ; Grahn, T (Jyvaskyla U.) ; Greenlees, P T (Jyvaskyla U.) ; Herzáň, A (Jyvaskyla U. ; Bratislava, Inst. Phys.) ; Julin, R (Jyvaskyla U.) ; Juutinen, S (Jyvaskyla U.) ; Konki, J (Jyvaskyla U. ; CERN) ; Leino, M (Jyvaskyla U.) et al.
We have identified an isomeric state in $^{201}$Fr for which we propose a spin and parity of $13/2^+$, and interpret it as arising from the $\pi(i_{13/2})$ configuration. A half-life of 720(40) ns was measured, corresponding to $B(M2)=0.17(2)$ W.u., in good agreement with those of other $13/2^+ \to 9/2^- [\pi (i_{13/2}) \to \pi(h_{9/2})]$ transitions observed in other nuclei in the region.

/ Petrache, C M (CSNSM, Orsay) ; Minkov, N (Sofiya, Inst. Nucl. Res.) ; Nakatsukasa, T (Tsukuba U. ; Nishina Ctr., RIKEN) ; Lv, B F (CSNSM, Orsay ; Lanzhou, Inst.

Experimental signatures of moderately enhanced octupole correlations at high spin in $^{136}\mathrm{Nd}$ are indicated for the first time. The extracted dipole moments of two negative-parity bands are only two times smaller than those of the lanthanide nuclei with $N≈90$ which present well-established octupole correlations. [...]

Excited states in $^{217}$Ra populated in the α decay of $^{221}$Th
/ Parr, E (West Scotland U. ; SUPA, UK) ; Smith, J F (West Scotland U. ; SUPA, UK) ; Greenlees, P T (Jyvaskyla U.) ; Auranen, K (Jyvaskyla U.) ; Chapman, R (West Scotland U. ; SUPA, UK) ; Cullen, D M (Manchester U.) ; Grahn, T (Jyvaskyla U.) ; Grocutt, L (West Scotland U. ; SUPA, UK) ; Herzáň, A (Jyvaskyla U. ; Bratislava, Inst. Phys.) ; Herzberg, R D (Liverpool U.) et al.
Fine structure in the α decay of $^{221}_{90}$Th, populating excited states in $^{217}_{88}$Ra, was studied using αγ-coincidence spectroscopy. Two α-decay branches from $^{221}$Th have been newly observed, with $E_{\alpha} \mathrm{(keV)} [b_{\alpha}(\%)]=7951(8)[0.14(3)]$ and $8247(3)[1.51(12)]$, together with three previously known branches.

High-spin states of $^{218}$Th
/ O'Donnell, D (SUPA, UK ; Liverpool U. ; IIT, Roorkee) ; Page, R D (Liverpool U.) ; Grahn, T (Jyvaskyla U.) ; Ali, F A (Liverpool U. ; Sulaimaniya U.) ; Auranen, K (Jyvaskyla U.) ; Capponi, L (SUPA, UK) ; Carroll, R J (Liverpool U.) ; Chishti, M M R (SUPA, UK) ; Drummond, M C (Liverpool U.) ; Greenlees, P T (Jyvaskyla U.) et al.
High-spin states in the $N = 128$ nucleus $^{218}$Th have been investigated following fusion–evaporation reactions, using the recoil-decay tagging technique. Due to the short-lived nature of the ground state of $^{218}$Th prompt $\gamma$ rays have been correlated with the $\alpha$ decay of the daughter nucleus $^{214}$Ra. [...]
