  • [hal-01645840] Losses and depolarization of ultracold neutrons on neutron guide and storage materials

    13 mai, par (V. Bondar), V. Bondar
    At Institut Laue-Langevin (ILL) and Paul Scherrer Institute (PSI), we have measured the losses and depolarization probabilities of ultracold neutrons on various materials: (i) nickel-molybdenum alloys with weight percentages of 82/18, 85/15, 88/12, 91/9, and 94/6 and natural nickel Ni100, (ii) (...)
  • [hal-01952936] Magnetic field uniformity in neutron electric dipole moment experiments

    24 avril, par (C. Abel), C. Abel
    Magnetic-field uniformity is of the utmost importance in experiments to measure the electric dipole moment of the neutron. A general parametrization of the magnetic field in terms of harmonic polynomial modes is proposed, going beyond the linear-gradients approximation. We review the main (...)
  • [in2p3-02067129] Appréhender le stock de métal monnayé au IVè siècle après J.-C.

    29 mars, par (Pierre-Marie Guihard), Pierre-Marie Guihard
    Parmi les thématiques abordées en numismatique à l’aide de l’archéométrie, les recherches spécifiques sur le stock de métal monnayé au ive siècle s’avèrent fascinantes mais délicates. Afflux de nouvelles ressources métalliques, refontes volontaires de monnaies : tous ces phénomènes sont de grande conséquence (...)
  • [hal-01725006] How sharp is the transition into the $N=20$ island of inversion for the Mg isotopes ?

    29 mars, par (B. Fernández-Domínguez), B. Fernández-Domínguez
    The N=20 island of inversion is an excellent playground for testing shell model calculations. The Mg chain is a region of shell evolution still far from being well understood. In this paper we present preliminary results of a single-neutron knockout experiment from 31Mg performed at GANIL to (...)
  • [hal-01719652] Re-examining the transition into the $N=20$ island of inversion : Structure of $^{30}$Mg

    29 mars, par (B. Fernández-Domínguez), B. Fernández-Domínguez
    Intermediate energy single-neutron removal from 31 Mg has been employed to investigate the transition into the N=20 island of inversion. Levels up to 5 MeV excitation energy in 30 Mg were populated and spin-parity assignments were inferred from the corresponding longitudinal momentum (...)
