[en] The ⁴P_J waves in nucleon-deuteron scattering were analyzed using proton-deuteron and neutron-deuteron data at E_N=3 MeV. New sets of nucleon-nucleon ³P_j phase shifts were obtained that may lead to a better understanding of the long-standing A_y(θ) puzzle in nucleon-deuteron elastic scattering. However, these sets of ³P_j phase shifts are quite different from the ones determined from both global phase-shift analyses of nucleon-nucleon data and nucleon-nucleon potential models. copyright 1998 The American Physical Society

[en] The experimental program supported by the present grant is a continuation of the work supported under DOE Contract AS05-76ER04449. More detailed discussion of the experimental apparatus and earlier activities can be found in annual reports for that contract. The primary objective of the program the is investigation of the nucleon-nucleon (NN) interaction, in the medium-energy region, in both elastic and inelastic channels. This paper reviews experiments dealing with these types of high energy collisions. 41 refs

[en] An overview of nuclear probes of three symmetries is given from an experimentalist's perspective. The symmetries discussed are isospin (I), parity (P) and time reversal (T). 23 refs., 4 figs

[en] In this paper a method s outlined to approximate nuclear potentials by separable expansions and solve algebraically the scattering problem in both the single-channel and multi-channel case. As an example we calculate phase shifts and polarization observables in proton-neutron scattering, with Reid soft core potential, at E_lab = 50 MeV

[en] The authors discuss the bandhead energies of two-quasiparticle states expected to appear in the excitation spectra of doubly odd Lu isotopes calculated on a quantitative evaluation of the zero range residual n-p interaction and compared with the available experimental information to deduce the deformed orbital configurations. Predictions are made about the expected locations of several as yet unobserved states

[en] We show that fully aligned neutron-proton pairs play a crucial role in the low-energy spectroscopy of nuclei with valence nucleons in a high-j orbital. Their dominance is valid in nuclei with valence neutrons and protons in different high-j orbitals as well as in N = Z nuclei, where all nucleons occupy the same orbital. We demonstrate analytically this generic feature of the neutron-proton interaction for a variety of systems with four valence nucleons interacting through realistic, effective forces. The dominance of fully aligned neutron-proton pairs results from the combined effect of (i) angular momentum coupling and (ii) basic properties of the neutron-proton interaction. (authors)

[en] This article is an extension of our recent studies of Ψ and ϒ production cross-sections in proton–proton collisions at the LHC with E = √S = 8.0 TeV to E = 13 TeV. (author)

[en] Hadron and quark exchange contributions to spin symmetries at 90⁰ in hadron elastic scattering are investigated. The angular distribution of scattering cross sections is considered for incident protons with contributions from nonflip and double-flip amplitudes for states of parallel and antiparallel spins. 5 refs
