Binding Energy of Ne2+ from Ion Scattering Data

The mixing of scalar mesons is introduced into the baryon-baryon system in the chiral SU(3) quark model to further dynamically investigate the Di-omega state by using the same parameters as those in reasonably describing the experimental hyperon-nucleon and nucleon-nucleon scattering data. Two different mixings of scalar mesons, the ideal mixing and 19° mixing, are discussed, and compared with no mixing. The results show that it is still deeply bound state if 19° mixing is adopted, the same as those of no mixing. However, for ideal mixing, the binding energy is reduced quite a lot, yet it is still a bound state.

Microscopic Optical Potential

In the present work we describe our results concerning the calculation of equation of state of symmetric zero temperature nuclear matter and the microscopic optical potential using the soft-core Argonne inter-nucleon potentials in first order Brueckner–Hartree–Fock (BHF) theory. The nuclear matter saturates at a density 0.228 nucleon/fm 3 with 17.52 MeV binding energy per nucleon for Argonne av-14 and at 0.228 nucleon/fm 3 with 17.01 MeV binding energy per nucleon for Argonne av-18. As a test case we present an analysis of 65 and 200 MeV protons scattering from 208 Pb . The Argonne av-14 has been used for the first time to calculate nucleon optical potential in BHF and analyze the nucleon scattering data. We also compare our reaction matrix results with those using the old hard-core Hamada–Johnston and the soft-core Urbana uv-14 and Argonne av-18 inter-nucleon potentials. Our results indicate that the microscopic potential obtained using av-14 gives marginally better agreement with the experimental data than the other three Hamiltonians used in the present work.

Scan Data

The atomic arrangement of the Si(llO) 5x1 reconstructed surface has been studied by low energy ion scattering. The experimentally measured incident angle scan data were compared with the results of computer simulations for various structural models. Although detailed quantitative interpretation of the full range of ion scattering data is difficult to achieve, there is clear evidence for a major reconstruction of the surface. A reasonable fit for the adatom model between the experimental results and computer simulation suggests that the clean Si(llO) 5x1 surface consists of a mixture of 5x1, 5x4 and 5x5 structures, possibly partially disordered along the [flO] direction. The different adatom and rest atom sites have been determined by fitting the calculation with the experimental data. However, there is no other existing experimental evidence, at this time, to support the adatom or rest atom height.

Experimental Binding Energy

Using the two-channel separable potentials of Nogami and Satoh, which are fitted to the hyperon-nucleon scattering data, the Λ binding energy in [Formula: see text] has been calculated using the model of Law and Nguyen. We find that the binding energy is sensitive to the coupling to the Σ channel. The results indicate that it is possible to obtain agreement with the experimental binding energy of [Formula: see text].

A self-consistent Brueckner calculation of the binding energy and single-particle energies of 16O and 40Ca is carried out employing an effective interaction which is determined directly from the two-body scattering data. The interaction is described by its harmonic-oscillator matrix elements. It is found that the results are quite sensitive to the form of the phase shift at high energies.
