Reactions of the halo systems 11Be and 11Li (at 460 280 MeV/nucleon) with a carbon target demonstrate that ( n+9Li) has an (unbound) l=0 ground state very close to threshold. The neutron appreciable (1s1/2)2 (0p1/2)2 components.Received 20 December 1994DOI:https://doi.org/10.1103/PhysRevLett.75.1719©1995 American Physical Society
The nuclear response of a medium-mass nucleus ${(}^{136}$Xe) to electromagnetic excitation in near-relativistic heavy-ion collision was investigated the ${\mathrm{reaction}}^{136}$Xe(0.7A GeV)+Pb. From an exclusive measurement neutron decay excited $^{136}\mathrm{Xe}$ projectiles, strong excitations giant resonances and, particular, double isovector dipole resonance were identified. A energy 28.3\ifmmode\pm\else\textpm\fi{}0.7 MeV, width 6.3\ifmmode\pm\else\textpm\fi{}1.6 and total cross...
We present data on collective flow of neutrons in collisons 197Au + at 400 MeV/nucleon. The azimuthal distribution about the beam axis is investigated with respect to reaction plane as determined from light charged particles. ''squeezeout'' neutrons, perpendicular plane, observed for first time. Quantitative agreement a high level accuracy found between behavior and hydrogen ions.Received 29 April 1993DOI:https://doi.org/10.1103/PhysRevLett.71.963©1993 American Physical Society
Neutron angular distributions from violent break-up reactions of 11Li and 11Be have been measured at 28 MeV/u 280 41 460 MeV/u, respectively. The derived neutron momentum show a narrow component in transverse that is within uncertainties independent beam energy target charge. This suggested to be simply related the distribution loosely bound halo neutron(s) projectiles.
The reconstruction of vertices corresponding to proton-proton collisions in ATLAS is an essential element event used many performance studies and physics analyses. During Run-1 the LHC, has employed iterative approach vertex finding. In order improve flexibility algorithm ensure continued for very high numbers simultaneous Run-2 LHC beyond, a new seeding finding been developed inspired by image techniques. This note provides brief outline how reconstructed tracks are create likely event,...
Presented in this contribution are methods currently developed and used by the ATLAS collaboration to measure performance of primary vertex reconstruction algorithms. With increasing instantaneous luminosity at LHC, many proton-proton collisions occur simultaneously one bunch crossing. The correct identification from a hard scattering process knowledge number additional pile-up interactions is crucial for physics analyses. Under high conditions, effects like splitting into or reconstructing...
Abstract Maintaining the huge grid computing facilities for LHC experiments and replacing their hardware every few years has been very expensive. The California State University (CSU) ATLAS group recently received $250,000 AWS cloud credit from CSU Chancellor’s Office to build first virtual US Tier 3 explore solutions ATLAS. We will use this award set up full environments on physics analysis frame works, MC generation, simulation production. also develop policies members submit jobs an...
