    No radial excitations in low energy QCD. I. Diquarks and classification of mesons by Friedmann, Tamar

    Published 2016
    “…The classification also leads to the introduction of isorons (iso-hadrons), which are analogs of atomic isotopes, and their magic quantum numbers, which are analogs of the magic numbers of the nuclear shell model. The magic quantum numbers of isorons match the quantum numbers expected for low-lying glueballs in lattice QCD. …”

    Precision measurement of the magnetic octupole moment in 45Sc as a test for state-of-the-art atomic- and nuclear-structure theory by R.P. de Groote, J. Moreno, J. Dobaczewski, Á. Koszorús, I. Moore, M. Reponen, B.K. Sahoo, C. Yuan

    Published 2022-04-01
    “…With a single valence proton outside of a magic calcium core, scandium is ideally suited to test a variety of nuclear models, and to investigate in-depth the many intriguing nuclear structure phenomena observed within the neighbouring isotopes of calcium. We perform nuclear shell-model calculations of Ω, and furthermore explore the use of Density Functional Theory for evaluating Ω. …”

    Microscopic calculation of the β− decays of 151Sm, 171Tm, and 210Pb with implications to detection of the cosmic neutrino background by J. Kostensalo, J. Kotila, J. Suhonen

    Published 2023-05-01
    “…These ff-nu β− transitions have non-trivial electron spectral shapes with transition nuclear matrix elements (NMEs) computed by using the microscopic Interacting Boson-Fermion Model (IBFM-2) for the decays of 151Sm and 171Tm, and the nuclear shell model (NSM) for the decay of 210Pb. Within the respective Q windows, the computed ff-nu electron spectral shapes deviate maximally at sub-percent level from the universal allowed shape, except for the transition Pb210(0g.s.+)→Bi210(1g.s.−), where the maximal deviation is some 2.7%. …”

    Two-neutrino ββ decay of 136Xe to the first excited 0+ state in 136Ba by L. Jokiniemi, B. Romeo, C. Brase, J. Kotila, P. Soriano, A. Schwenk, J. Menéndez

    Published 2023-03-01
    “…We use different many-body methods: the quasiparticle random-phase approximation (QRPA) framework, the nuclear shell model, the interacting boson model (IBM-2), and an effective field theory (EFT) for β and ββ decays. …”

    Many-body factorization and position–momentum equivalence of nuclear short-range correlations by Cruz Torres, Reynier, Lonardoni, D., Weiss, R., Piarulli, M., Barnea, N., Higinbotham, D. W., Piasetzky, E., Schmidt, Axel William, Weinstein, L. B., Wiringa, R. B., Hen, Or

    Published 2021
    “…While mean-field approximations, such as the nuclear shell model, provide a good description of many bulk nuclear properties, they fail to capture the important effects of nucleon–nucleon correlations such as the short-distance and high-momentum components of the nuclear many-body wave function1. …”

    Published 2024-02-01
    “…The nuclear shell model has been very successful in describing various properties of nuclei, especially in the neighborhood of the closed shells, where the configuration space is usually small but good enough for the construction of the nuclear wave function. …”

    Re-Evaluation of the Nuclear Magnetic Octupole Moment of <sup>209</sup>Bi by Jiguang Li, Gediminas Gaigalas, Jacek Bieroń, Jörgen Ekman, Per Jönsson, Michel Godefroid, Charlotte Froese Fischer

    Published 2022-11-01
    “…The present extracted octupole moment was consistent with all the available values but the one obtained in the single-particle nuclear shell model approximation. This observation supports the previous finding that nuclear many-body effects, such as the core polarization, significantly contribute to the nuclear magnetic octupole moment in the case of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mrow></mrow><mn>209</mn></msup></semantics></math></inline-formula>Bi.…”

    High-precision measurement of a low Q value for allowed β−-decay of 131I related to neutrino mass determination by T. Eronen, Z. Ge, A. de Roubin, M. Ramalho, J. Kostensalo, J. Kotila, O. Beliushkina, C. Delafosse, S. Geldhof, W. Gins, M. Hukkanen, A. Jokinen, A. Kankainen, I.D. Moore, D.A. Nesterenko, M. Stryjczyk, J. Suhonen

    Published 2022-07-01
    “…Our measurement confirms that the β−-decay to the 9/2+ excited state at 971.22(13) keV in 131Xe is energetically allowed with a Q value of 1.03(23) keV while the decay to the 7/2+ state at 973.11(14) keV was found to be energetically forbidden. Nuclear shell-model calculations with established two-body interactions, alongside an accurate phase-space factor and a statistical analysis of the logft values of known allowed β decays, were used to estimate the partial half-life for the low-Q-value transition to the 9/2+ state. …”
