“…Results for the unpolarized differential cross section (dσ/dΩ), the polarization (P), the depolarization (D), the tensor asymmetry (A yy )and triple scattering parameters A and R are shown in Fig. ( 5) to (7) for pp and pn at three different energies, namely 50, 125 and 200 MeV. In general, our HLF parameterization provides an excellent description of the empirical scattering observables.…”

“…Moreover, this model has a physical basis in the one-boson-exchange (OBE) picture, since the values of the real meson-nucleon coupling constants (at energies higher than 200 MeV) are similar to those arising from more sophisticated OBE models [1]. In addition to being employed as the basic NN interaction driving the dominant reaction mechanism in several relativistic scattering models of nucleon-induced reactions, the HLF model has also been applied to extract relativistic microscopic optical potentials [2,5,6,7] for studying elastic proton scattering from stable nuclei, as well as for generating scattering wave functions for evaluating transition matrix elements in various relativistic distorted wave models [5,6]. More specifically, the latter microscopic optical potentials are generated by folding the HLF t-matrix with the relevant relativistic mean field Lorentz densities via the so-called tρ-approximation.…”

For laboratory kinetic energies between 50 and 200 MeV, we focus on generating an energydependent Lorentz covariant parameterization of the on-shell nucleon-nucleon (NN) scattering amplitudes in terms of a number of Yukawa-type meson exchanges in first-order Born approximation.This parameterization provides a good description of NN scattering observables in the energy range of interest, and can also be successfully extrapolated to energies between 40 and 300 MeV.

“…43 and 44). However, a quantitative analysis of the (p, p ′ ) data is hampered by the dependence of the extracted spin-M 1 strengths on the choice of the effective projectile target interaction, which can lead to variations up to about 40% (Hofmann et al, 2007). Thus, it is important to find other means to disentangle the spin and orbital parts.…”

Magnetic dipole excitations in nuclei: Elementary modes of nucleonic motion

2010

View full text Add to dashboard Cite

The nucleus is one of the most multi-faceted many-body systems in the universe. It exhibits a multitude of responses depending on the way one 'probes' it. With increasing technical advancements of beams at the various accelerators and of detection systems the nucleus has, over and over again, surprised us by expressing always new ways of 'organized' structures and layers of complexity. Nuclear magnetism is one of those fascinating faces of the atomic nucleus we discuss in the present review. We shall not just limit ourselves to presenting the by now very large data set that has been obtained in the last two decades using various probes, electromagnetic and hadronic alike and that presents ample evidence for a low-lying orbital scissors mode around 3 MeV, albeit fragmented over an energy interval of the order of 1.5 MeV, and higher-lying spin-flip strength in the energy region 5 − 9 MeV in deformed nuclei, nor to the presently discovered evidence for low-lying proton-neutron isovector quadrupole excitations in spherical nuclei. To the contrary, we put the experimental evidence in the perspectives of understanding the atomic nucleus and its various structures of well-organized modes of motion and thus enlarge our discussion to more general fermion and bosonic many-body systems.

“…The theorethical and experimental study of photonic NOON states [5] has lead to the experimental a posteriori generation of two, three and four photons states [6,7,8] and to the conditional generation of a state with N = 2 [9]. Furthermore, very recently schemes for the generation of path-entangled NOON states with high value of fidelity and arbitrary N have been proposed [10,11]. However, the weak value of the generated number of photons strongly limits the potential applications to quan-tum lithography and quantum metrology.…”

Amplification of polarization NOON states

et al. 2009

NOON states are path entangled states which can be exploited to enhance phase resolution in interferometric measurements. In the present paper we analyze the quantum states obtained by optical parametric amplification of polarization NOON states. First we study, theoretically and experimentally, the amplification of a 2-photon state by a collinear Quantum Injected Optical Parametric Amplifier (QIOPA). We compared the stimulated emission regime with the spontaneous one, studied by Sciarrino et al. (PRA 77, 012324), finding comparable visibilities between the two cases but an enhancement of the signal in the stimulated case. As a second step, we show that the collinear amplifier cannot be successfully used for amplifying N-photon states with N>2 due to the intrinsic \lambda/4 oscillation pattern of the crystal. To overcome this limitation, we propose to adopt a scheme for the amplification of a generic state based on a non-collinear QIOPA and we show that the state obtained by the amplification process preserves \lambda/N feature and exhibits a high resilience to losses. Furthermore, an asymptotic unity visibility can be obtained when correlation functions with sufficiently high order M are analyzed.Comment: 10 pages, 9 figure
