In-medium nuclear interactions of low-energy hadrons
2007, Physics ReportsExotic atoms provide a unique laboratory for studying strong interactions and nuclear medium effects at zero kinetic energy. Experimental and theoretical developments of the last decade in the study of exotic atoms and some related low-energy reactions are reviewed. The exotic atoms considered are of , and also the so far unobserved atoms. The analysis of these atomic systems consists of fitting density-dependent optical potentials to comprehensive sets of data of strong-interaction level shifts, widths and yields across the periodic table. These provide information on the in-medium hadron–nucleon t matrix over a wide range of densities up to central nuclear densities. For pions, the review focuses on the extraction of the in-medium s-wave interaction from pionic atoms, which include also the deeply bound atomic states recently observed at GSI in isotopes of Sn and Pb. Also included are recent measurements at PSI of elastic scattering of on Si, Ca, Ni and Zr at 21.5 MeV. The experimental results are analyzed in the context of chirally motivated -nuclear potentials, and the evidence for partial restoration of chiral symmetry in dense nuclear matter is critically discussed. For antikaons, we review the evidence from atoms, and also from low-energy scattering and reaction data for and against a deep -nucleus potential of 150–200 MeV attraction at nuclear matter density. The case for relatively narrow deeply bound atomic states is made, essentially independent of the potential-depth issue. Recent experimental suggestions from KEK and DANE (Frascati) for signals of -nuclear deeply bound states are reviewed, and dynamical models for calculating binding energies and widths of -nuclear states are discussed. For kaons we review the evidence, from total and reaction cross section measurements at the AGS (BNL) on Li, C, Si and Ca at, for significant absorptivity of beyond that expected from within the impulse approximation. Attempts to explain the extra absorptivity for the relatively weak interaction of K mesons in terms of a hypothetical exotic pentaquark strength are reviewed. For antiprotons the exceptionally broad data base due to the recent results of the PS209 collaboration at CERN are analyzed, together with results of radiochemical experiments. We discuss the dependence of the phenomenological -nucleus interaction on the model adopted for the neutron density, showing how the neutron densities favored by our comprehensive analysis are compatible with densities from other sources, including our own analysis of pionic atoms. It is also shown how the strong absorptivity of the -nucleus interaction, which leads to the prediction of saturation of widths in deeply bound -atom states, also explains the observed saturation effects in low-energy annihilation on nuclei. For hyperons we review the evidence, from continuum hypernuclear spectra obtained recently at KEK on C, Si, Ni, In and Bi, for substantial repulsion in the -nucleus interaction, and the relationship to the inner repulsion established earlier from the density-dependence analysis of atoms and by analyses of past AGS experiments.
Lastly, for hyperons we review prospects of measuring X-ray spectra in atoms and thereby extracting meaningful information on the -nucleus interaction. The significance of the latter to the physics of hypernuclei and to extrapolation into multistrange hypernuclei are briefly reviewed.
Strong interaction physics from hadronic atoms
1997, Physics ReportHadronic atoms provide a unique laboratory for studying strong interactions and nuclear medium effects at zero kinetic energy. Previous results from analyses of strong-interaction data consisting of level shifts, widths and yields in π−, K−, p̄ and ∑− atoms are reviewed. Recent results from fits to comprehensive sets of data in terms of density-dependent optical potentials that respect the low-density limit, where the interaction tends to the free hadron nucleon value, are discussed. The importance of using realistic nuclear density distributions is highlighted. The introduction of density dependence in most cases significantly improves the fit to the data and leads to some novel results. For K− atoms, a substantial attraction of order 200 MeV in nuclear matter is suggested, with interesting repercussions for K̄ condensation and the evolution of strangeness in high-density stars. For p̄ atoms it is found that a reasonable p-wave strength can be accommodated in the fitted optical potential, in agreement with the energy dependence observed for some low-energy p̄N reactions. For ∑− atoms, the fitted potential becomes repulsive inside the nucleus, implying that Σ hyperons generally do not bind in nuclei in agreement with recent measurements. This repulsion significantly affects calculated masses of neutron stars.
Low-energy pion-nucleus interaction and nuclear relativism
1992, Nuclear Physics, Section AThe s-wave pion-nucleus repulsion problem may be solved by taking into account nuclear relativism within the Walecka model.
Measurement of the pionic 2p1s X-ray transition in <sup>22</sup>Ne
1992, Nuclear Physics, Section AThe energy and line width of the π− 22Ne 2pls X-ray transition have been measured using an isotopically pure liquid 22Ne target and a Compton suppression system. The values obtained are for the energy 230.9±0.3 keV, and for the width 10.8±0.7 keV. The data from a previous measurement on natural neon have been reanalyzed using these values. Revised values for 20Ne are for the energy 239.2±0.12 keV, and for the width 15.5±0.2 keV. Calculations with several versions of the optical potential have been carried out to investigate the sensitivity to the isovector and matter distribution parameters. Whike the measured energy agrees well with the calculations, the strong interaction width differs from most theoretical values by about 2 keV. Comparison with the previous result on natural Ne shows a strong isotope effect in the width of the 1s level.
The isoscalar pion-nucleus interaction from pionic atoms
1987, Physics Letters BThe analysis of pionic atom data of 1s and 2p levels for N = Z spin-zero nuclei, in terms of an improved optical potential is presented. We find a strong (unexplained) s-wave repulsion and evidence for finite-range effects. The need for a relativistic treatment of the pion—nucleus interaction is discussed.
Medium-polarization models and a realistic estimate of rescattering in the S-wave pion-nucleus optical potential
1986, Physics Letters BThe rescattering contribution to the second-order S-wave pion-nucleus optical potential is calculated in a model of nuclear medium polarization which includes nucleon-hole-pair contributions as well as those of isobar-hole pairs. The resulting value for (b0)effective is found (for g′= 0.6) to be in excellent agreement with that obtained in recent fits to pionic atom 1s level shift data for the fitting scenario which takes Re B0 = 0.
