Nuclear Masses from First Principles

  • Hermann G. Kümmel

Abstract

In this talk I want to review the present status of the calculation of nucleon masses from “first principles”. How “first” the principles are, depends on one’s viewpoint. I shall take the position that we want to compute nuclear properties from two body nucleon-nucleon (NN) potentials which in turn have been fixed by optimizing the description of two nucleon data (scattering and bound state of the deuteron). What the theorist then has to do is to solve the A = N + Z body problem as good as he can and sell the results to the experimentalists. Such a procedure is legitimate as long as the following two points are observed:
  1. i)

    it is made sure that the (necessarily approximate) procedure used in many body theory converges

     
  2. ii)

    the basic concept of using two body potentials always is kept in mind: knowing that in fact there is meson exchange instead of potentials and baryonic resonances in addition to mere nucleons, a complete agreement between such a simple description and nature cannot be expected. Yet it is of course interesting and important to know to what extent “pure many nucleon theory” is valid.
