[hal-02151615] Impact of electron capture rates on nuclei far from stability on core-collapse supernovae
13 juin, par ano.nymous@ccsd.cnrs.fr.invalid (Aurélien Pascal), Aurélien PascalThe impact of electron-capture (EC) cross sections on neutron-rich nuclei on the dynamics of core-collapse during infall and early post-bounce is studied performing spherically symmetric simulations in general relativity using a multigroup scheme for neutrino transport and full nuclear (...) -
[in2p3-00986882] Distributed feedback lasing of commercial liquid scintillators
11 juin, par ano.nymous@ccsd.cnrs.fr.invalid (M. Michel), M. MichelIt is shown that lasing can be achieved in commercial organic liquid scintillators. Using a dynamic grating induced by an interference pattern in the scintillator volume, distributed feedback lasing is shown to occur in four out of five commercial liquid scintillators that have been (...) -
[hal-01853671] Magnetic field distribution in magnetars
6 juin, par ano.nymous@ccsd.cnrs.fr.invalid (Debarati Chatterjee), Debarati ChatterjeeUsing an axisymmetric numerical code, we perform an extensive study of the magnetic field configurations in non-rotating neutron stars, varying the mass, magnetic field strength and the equation of state. We find that the monopolar (spherically symmetric) part of the norm of the magnetic field (...) -
[hal-01554412] Towards high-resolution laser ionization spectroscopy of the heaviest elements in supersonic gas jet expansion
3 juin, par ano.nymous@ccsd.cnrs.fr.invalid (R. Ferrer), R. FerrerResonant laser ionization and spectroscopy are widely used techniques at radioactive ion beam facilities to produce pure beams of exotic nuclei and measure the shape, size, spin and electromagnetic multipole moments of these nuclei. However, in such measurements it is difficult to combine a (...) -
[in2p3-00840026] Implementation of an imaging spectrometer for localization and identification of radioactive sources
3 mai, par ano.nymous@ccsd.cnrs.fr.invalid (Hermine Lemaire), Hermine LemaireSpatial localization of radioactive sources is currently a main issue interesting nuclear industry as well as homeland security applications, and can be achieved using gamma cameras. For several years, CEA LIST has been designing a new system, called GAMPIX, with improved sensitivity, (...)
