Report

Pseudo-spin Symmetry and Relativistic Single-nucleon Wave Functions

Autor: Ginocchio, Joseph N., Madland, David G.

Publikováno v: Phys.Rev.C57:1167-1173,1998

We show that the occurrence of approximate pseudo-spin symmetry in nuclei is connected with certain similarities in the relativistic single-nucleon wave functions of the corresponding pseudo-spin doublets. We perform a case study in which several exa

QCD Scales and Chiral Symmetry in Finite Nuclei

Autor: Madland, David G.

We report on our progress in the calculation of nuclear ground-state properties using effective Lagrangians whose construction is constrained by QCD scales and chiral symmetry. Good evidence is found that QCD and chiral symmetry apply to finite nucle

Progress in the Development of Global Medium-Energy Nucleon-Nucleus Optical Model Potentials

Autor: Madland, David G.

Two existing global medium-energy nucleon-nucleus phenomenological optical model potentials are described and compared with experiment and with each other. The first of these employs a Dirac approach (second-order reduction) that is global in project
