Bashkanov, H. Clement, T. Skorodko Categories: nucl-ex hep-ph \\ Based on measurements the branching ratios for the decay of the recently discovered dibaryon resonance $d^*(2380)$ into two-pion production channels and into the $np$ channel are evaluated. Possibilities for a decay into the isoscalar single-pion channel are discussed. Finally also the electromagnetic decay of $d^*(2380)$ is considered. \\ ( http://arxiv.org/abs/1502.07156 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:1502.07322 Date: Wed, 25 Feb 2015 20:04:54 GMT (173kb,D) Title: Nuclear clocks based on resonant excitation of gamma-transitions Authors: Ekkehard Peik, Maxim Okhapkin Categories: nucl-ex physics.atom-ph Comments: Invited review paper for Comptes Rendus de Physique, thematic issue 'The Measurement of Time' \\ We review the ideas and concepts for a clock that is based on a radiative transition in the nucleus rather than in the electron shell. This type of clock offers advantages like an insensitivity against field-induced systematic frequency shifts and the opportunity to obtain high stability from interrogating many nuclei in the solid state. Experimental work concentrates on the low-energy (about 8 eV) isomeric transition in Th-229. We review the status of the experiments that aim at a direct optical observation of this transition and outline the plans for high-resolution laser spectroscopy experiments. \\ ( http://arxiv.org/abs/1502.07322 , 173kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1502.07317 (*cross-listing*) Date: Wed, 25 Feb 2015 19:35:40 GMT (206kb) Title: A new measurement of the neutron detection efficiency for the NaI Crystal Ball detector Authors: M.

Wolfes Categories: physics.ins-det hep-ex nucl-ex \\ We report on a measurement of the neutron detection efficiency in NaI crystals in the Crystal Ball detector obtained from a study of single p0 photoproduction on deuterium using the tagged photon beam at the Mainz Microtron. The results were obtained up to a neutron energy of 400 MeV. They are compared to previous measurements made more than 15 years ago at the pion beam at the BNL AGS. \\ ( http://arxiv.org/abs/1502.07317 , 206kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1411.5602 (*cross-listing*) replaced with revised version Wed, 25 Feb 2015 01:44:58 GMT (152kb,D) Title: Pion-pion cross section from proton-proton collisions at the LHC Authors: B.Z.
