چکیده
We demonstrate a new approach to the analysis of extensive multi-energy data. For the case of d + 4 He, we produce a phase shift analysis covering for the energy range 3 to 11 MeV. The key idea is the use of a new technique for data-to-potential inversion which yields potentials which reproduce the data simultaneously over a range of energies. It thus effectively regularizes the extraction of phase shifts from diverse, incomplete and possibly somewhat contradictory data sets. In doing so, it will provide guidance to experimental-ists as to what further measurements should be made. This study is limited to vector spin observables and spin-orbit interactions. We discuss alternative ways in which the theory can be implemented and which provide insight into the ambiguity problems. We compare the extrapolation of these solutions to other energies. Majorana terms are presented for each potential component.

We demonstrate a new approach to the analysis of extensive multi-energy data. For the case of d + 4 He, we produce a phase shift analysis covering for the energy range 3 to 11 MeV. The key idea is the use of iterative perturbative data-to-potential inversion which can produce potentials which reproduce the data simultaneously over a range of energies. It thus effectively regularizes the extract...

We consider K − nucleon elastic and inelastic scattering in isospin symmetric nuclear matter. It is found that the proper description of the Λ(1405) resonance structure in nuclear matter requires a self-consistent approach. Then the Λ(1405) resonance mass remains basically unchanged, however, the resonance acquires an increased decay width as nuclear matter is compressed. The elastic and inelas...

We discuss a recent computation of Compton scattering on the deuteron at photon energies of order the pion mass. An interaction kernel is computed in baryon chiral perturbation theory and sewn to phenomenological deuteron wave functions. As an appetizer, we consider a computation of the pion-deuteron scattering length using this method.

We study the hyperfine splitting of an electron in hydrogen-like 209 Bi 82+. It is found that the hfs energy splitting can be explained well by considering the g-factor reduction due to the binding effect of a bound electron. We determine for the first time the experimental value of the magnetic moment of a tightly bound electron.
