ON THE RESTORATION OF GALILEAN INVARIANCE IN THE NUCLEAR MANY BODY PROBLEM — •Rayner Rodriguez, Karl W. Schmid, Amand Faessler, and Alexander Ivanov — Institut für Theoretische Physik der Universität Tübingen Auf der Morgenstelle 14, D-72076 Tübingen, Germany.

Full Galilean invariance is restored in the doubly magic closed shell nuclei ⁴He, ¹⁶O and ⁴⁰Ca using the projection onto the center of momentum rest frame before the nuclear wave function is determined by the Hartree-Fock variational method. A translationally invariant interaction of the Brink-Boeker type is used, as a first test, to study the effects of such a restoration on the total energy, charge densities and form factors.
