Gamma rays from excited states feeding a proton-emitting isomeric-state in 151Lu have been observed for the first time. Comparison with state-of-the-art nonadiabatic quasiparticle calculations indicates an oblately deformed, 3/2+ proton-emitting state with a quadrupole deformation of β2 = −0.11. The calculations suggest an increase in quadrupole deformation, to β2 = −0.18, with increasing spin which is understood in terms of the mixing of Nilsson states at the Fermi surface. It is also shown that the proton decay half-life is consistent with that from a 3/2+ state with a quadrupole deformation of β2 = −0.12.

    The lifetime of the (11/2+) state in the band above the proton-emitting (3/2+) state in 113Cs has been measured to be τ = 24(6) ps from a recoil-decay-tagged differential-plunger experiment. The measured lifetime was used ...
  • Measurements of isomeric yield ratios of fission products from proton-induced fission on natU and 232Th via direct ion counting 

    Rakopoulos, Vasileios; Lantz, Mattias; Al-Adili, Ali; Gorelov, Dmitry; Jokinen, Ari; Kolhinen, Veli; Mattera, Andrea; Moore, Iain; Penttilä, Heikki; Prokofiev, Alexander V.; Solders, Andreas; Pomp, Stephan (EDP Sciences, 2017)
    Independent isomeric yield ratios (IYR) of 81Ge, 96Y, 97Y, 97Nb, 128Sn and 130Sn have been determined in the 25 MeV proton-induced fission of natU and 232Th. The measurements were performed at the Ion Guide Isotope Separator ...
  • Effective axial-vector strength within proton-neutron deformed quasiparticle random-phase approximation 

    Delion, D. S.; Dumitrescu, A.; Suhonen, J. (American Physical Society, 2019)
    We use the available experimental Gamow-Teller β− and β+/EC (electron-capture) decay rates between 0+ and 1+ ground states in neighboring even-even and odd-odd nuclei, combined with 2νββ half-lives, to analyze the influence ...
  • Nanosecond-Scale Proton Emission from Strongly Oblate-Deformed 149Lu 

    Auranen, K.; Briscoe, A. D.; Ferreira, L. S.; Grahn, T.; Greenlees, P. T.; Herzáň, A.; Illana, A.; Joss, D. T.; Joukainen, H.; Julin, R.; Jutila, H.; Leino, M.; Louko, J.; Luoma, M.; Maglione, E.; Ojala, J.; Page, R. D.; Pakarinen, J.; Rahkila, P.; Romero, J.; Ruotsalainen, P.; Sandzelius, M.; Sarén, J.; Tolosa-Delgado, A.; Uusitalo, J.; Zimba, G. (American Physical Society (APS), 2022)
    Using the fusion-evaporation reaction 96Ru(58Ni,p4n)149Lu and the MARA vacuum-mode recoil separator, a new proton-emitting isotope 149Lu has been identified. The measured decay Q value of 1920(20) keV is the highest measured ...
  • Insights into the decomposition pathway of a lutetium alkylamido complex via intramolecular C–H bond activation
