Hadronic Resonance Production with ALICE at the LHC
Physics of Atomic Nuclei - Tập 85 - Trang 965-969 - 2023
S. Kiselev
We present recent results on short-lived hadronic resonances obtained by the ALICE experiment at LHC energies. Results include system-size and collision-energy evolution of transverse momentum spectra, yields and ratios of resonance yields to those of longer lived particles, and nuclear modification factors. The results are compared with model predictions and measurements at lower energies.
Current-carrying element based on second-generation high-temperature superconductor for the magnet system of a fusion neutron source
Physics of Atomic Nuclei - Tập 78 - Trang 1148-1154 - 2016
M. S. Novikov, D. P. Ivanov, S. I. Novikov, S. A. Shuvaev
Application of current-carrying elements (CCEs) made of second-generation high-temperature superconductor (2G HTS) in magnet systems of a fusion neutron source (FNS) and other fusion devices will allow their magnetic field and thermodynamic stability to be increased substantially in comparison with those of low-temperature superconductor (LTS) magnets. For a toroidal magnet of the FNS, a design of...... hiện toàn bộ

Strategies of Searches of the Angular Anisotropy of Fluxes of Galactic Electrons and Positrons by Means of the PAMELA Experiment Calorimeter
Physics of Atomic Nuclei - Tập 81 - Trang 721-729 - 2019
A. V. Karelin, S. A. Voronov
The possibility of studying the anisotropy of the total fluxes of electrons and positrons of high-energy (10 GeV to 1 TeV) cosmic rays in the PAMELA satellite-borne experiment by means of a calorimeter is considered. The procedure developed with aim of performing searches for this anisotropy is described along with the results of applying it to a test data sample.
Experimental upper limit on diffractive dissociation in muon-neutrino interaction with photoemulsion nuclei according to data of the E-128 experiment (Protvino)
Physics of Atomic Nuclei - Tập 67 - Trang 2166-2168 - 2004
O. K. Egorov, V. A. Ryabov
The phenomenon of diffractive dissociation is experimentally estimated for neutrino interaction with photoemulsion nuclei. The results are based on data obtained in the SCIP experiment performed in a neutrino beam at the U-70 accelerator (Protvino). The data sample subjected to analysis included 670 charged-current events corresponding to neutrino interactions in the vertex detector. Events in whi...... hiện toàn bộ
Reaction cross sections for exotic nuclei in the Glauber approach

Wave Functions and $${S}$$ Factor for a Composite System of Two Arbitrary-Mass Relativistic Spinor Quarks
Physics of Atomic Nuclei - Tập 84 - Trang 339-353 - 2021
Yu. D. Chernichenko
Exact solutions of relativistic quasipotential equations in the configuration representation are found for the $$s$$ -state wave function for a composite system of two arbitrary-mass relativistic spinor quarks interacting via a Coulomb-like chromodynamic potential. Composite systems who...... hiện toàn bộ
Phenomenological description of relativistic-quark interaction on the basis of the Dirac equation with the Cornell potential
Physics of Atomic Nuclei - Tập 80 - Trang 976-982 - 2017
A. J. Silenko, O. V. Teryaev
Relativistic-quark interaction is described phenomenologically on the basis of the Dirac equation with the Cornell potential. A general form of the initial equation involving the vector and scalar components of the Cornell potential is used for the case of an arbitrary relation between them. The Hamiltonian in the Foldy–Wouthuysen representation is derived in a general form with allowance for elec...... hiện toàn bộ
Nature of the pygmy resonance in continuous γ spectra

A. V. Voinov, A. Schiller, E. Algin, L. A. Bernstein, P. E. Garrett, M. Guttormsen, R. O. Nelson, J. Rekstad, S. Siem
Two-step-cascade spectra of the 171Yb(n, γγ)172Yb reaction have been measured using thermal neutrons. They are compared to calculations based on experimental values of the level density and radiative strength function obtained from the 173Yb(3He, aγ)172Yb reaction. The multipolarity of a 6.5(15) μ N 2 resonance at 3.3(1) MeV in the strength fun...... hiện toàn bộ
Deformation properties of the neutron-deficient odd-A Pt and Hg nuclei
Physics of Atomic Nuclei - - 2001
J. Sauvage, J. Libert, B. Roussière, D. Verney, L. Cabaret, J. E. Crawford, J. Genevey, G. Huber, F. Ibrahim, F. Le Blanc, J. K. P. Lee, J. Oms, J. Pinard
Nuclear and atomic spectroscopy measurements have provided a great number of data on the neutron-deficient Pt and Hg nuclei. The odd-A Pt and Hg with A<186 have a prolate shape, and the even-even isotopes have a triaxial shape, while the nuclear shape of the odd-A Pt and Hg with A>186 is still an open question. The energy of the low-lying levels and the nuclear moments have been calculated in the ...... hiện toàn bộ
