Excited states in the neutron-deficient N=84 nuclide 155Lu have been populated by using the 102Pd(58Ni,αp) reaction. The 155Lu nuclei were separated by using the gas-filled recoil ion transport unit (RITU) separator and implanted into the Si detectors of the gamma recoil electron alpha tagging (GREAT) spectrometer. Prompt γ-ray emissions measured at the target position using the JUROGAM Ge detector array were assigned to 155Lu through correlations with α decays measured in GREAT. Structures feeding the (11/2−) and (25/2−)α-decaying states have been revised and extended. Shell-model calculations have been performed and are found to reproduce the excitation energies of several of the low-lying states observed to within an average of 71 keV. In particular, the seniority inversion of the 25/2− and 27/2− states is reproduced.

Mass measurements of neutron-deficient nuclei and their implications for astrophysics
Kankainen, Anu; Novikov, Yuri; Schatz, H.; Weber, Christine (Springer, 2012)During the years 2005-2010 the double-Penning-trap mass spectrometer JYFLTRAP has been used to measure the masses of 90 ground and 8 isomeric states of neutron-deficient nuclides with a typical precision of better than ... -
Alpha decay spectroscopy of neutron-deficient astatine, radon and francium nuclei using a gas-filled separator
Enqvist, Timo (1996)Alpha particle decay properties (alpha particle energy and half-life) of neutron-deficient astatine, radon and francium isotopes are studied in this thesis. These nuclei in the close vicinity of the proton drip-line were ... -

Isomers of astrophysical interest in neutron-deficient nuclei at masses A = 81, 85 and 86
Kankainen, Anu; Vorobjev, Gleb; Eliseev, S.A.; Huang, Wenxue; Huikari, Jussi; Jokinen, Ari; Nieminen, Arto; Novikov, Yuri; Penttilä, Heikki; Popov, Andrey; Rinta-Antila, Sami; Schatz, H.; Seliverstov, Dmitry; Suslov, Yu.P.; Äystö, Juha (Springer, 2005)Decay properties of neutron-deficient exotic nuclei close to A=80 have been investigated at the IGISOL facility. The studied nuclei, 81Y, 81Sr, 81mKr, 85Nb, 85Zr, 86Mo and 86Nb, were produced by a 32S beam from the Jyväskylä ... -
In-beam spectroscopic studies of shape coexistence and collectivity in the neutron-deficient Z ≈ 82 nuclei
Julin, Rauno; Grahn, Tuomas; Pakarinen, Janne; Rahkila, Panu (Institute of Physics Publishing Ltd.; Institute of Physics, 2016)In the present paper we focus on studies of shape coexistence in even-mass nuclei in the neutron-deficient Pb region. They are based on experiments carried out using tagging techniques in the Accelerator Laboratory of the ...
