The muon-proton and muon-deuteron inclusive deep inelastic scattering cross sections were measured in the kinematic range 0.002 < × 0.60 0.5 Q2 75 GeV2 at incident muon energies of 90, 120, 200 280 GeV. These results are based on full data set collected by New Muon Collaboration, including taken with a small angle trigger. extracted values structure functions F2p F2d good agreement those from other experiments. cover sufficient y to allow determination ratio longitudinally transversely...
The two-plasmon instability in warm inhomogeneous plasma for a normally incident pump is considered. complex eigenfrequencies of the absolute are obtained by reducing linearized fluid equations to Schrödinger equation wavenumber space. These eigenvalues several ways. One combining perturbation expansion powers reciprocal scale length with WKB theory. resulting algebraic solved three analytical approximations and direct numerical solution. A second way analysis using an interactive computer...
A general calculation of the polarization resulting from nuclear reactions is made by means $S$ matrix and Racah formalisms. All sums over magnetic quantum numbers are performed; expressed as a series in associated Legendre polynomials, each coefficient being manifestly real. selection rules follow immediately requirements for nonvanishing $X$ coefficients. The only restriction required to two-body break-up.Higher spin tensor moments complete specification state beam particles greater than...
Anisotropic patchy particles have become an archetypical statistical model system for associating fluids. Here, we formulate approach to the Kern–Frenkel via classical density functional theory describe positionally and orientationally resolved equilibrium distributions in flat wall geometries. The is split into a reference part averaged orientational mean-field approximation. To bring kernel form suitable machine learning (ML) techniques, expansion invariants proper incorporation of...

Laser-plasma interaction experiments have been carried out on the OMEGA laser system [T. R. Boehly et al., Opt. Commun. 133, 495 (1997)] under plasma conditions representative of peak a 1.5 MJ direct-drive pulse proposed for National Ignition Facility (NIF). Plasmas formed by exploding 18–20 μm thick CH foils and irradiating solid targets from one side, using up to 20 kJ energy with phase plates installed all beams. These plasmas NIF are predicted electron temperatures 4 keV density scale...
AbstractThe attenuation of fast neutrons by long, thin air ducts in shields is considered from a simple phenomenological point view. It shown that the wall-scattered flux straight duct small compared to uncollided which travel directly one end other. An expression for due bend derived and this generalized case several bends.
We investigate the orientational properties of a homogeneous and inhomogeneous tetrahedral four-patch fluid (Bol–Kern–Frenkel model). Using integral equations, either (i) HNC or (ii) modified scheme with simulation input, full dependence pair direct correlation functions is determined. Density functionals for problem are constructed via two different methods. The first, molecular density functional theory, utilizes function an isotropic hard-sphere bridge functional. second method, machine...
The flux of radiation emitted from an inhomogeneous plasma by stimulated Raman and Brillouin scattering is calculated with a source that includes both bremsstrahlung longitudinal wave noise sources. Significant enhancement the above found for alone are nonthermal but stable velocity distributions.
Four methods for nuclear polarization and alignment are discussed compared. In particular, a general theorem regarding the leading term in expression by hfs coupling with external field is obtained. A method derived treating computation of higher order terms expansions these quantities, as well use complicated hamiltonians, application made to three cases interest. It shown that very small, interest, compared terms.
The properties of ion-acoustic waves in a plasma are investigated by analytically solving the electron Fokker-Planck (FP) and cold-ion fluid equations for arbitrary electron-ion (e-i) collision strength. This is achieved developing reduced form FP equation with generalized frequency. It demonstrated that effective wave damping can be treated as combination collisional collisionless mechanisms. Contrary to several previous reports, weak e-i collisions shown increase rate above Landau limit.
