GROUND STATES AND EXCITED STATES OF HYPERNUCLEI IN RELATIVISTIC MEAN FIELD APPROACH

Abstract

Hypernuclei have been studied within the framework of Relativistic Mean Field theory. The force FSU Gold has been extended to include hyperons. The effective hyperon–nucleon and hyperon–hyperon interactions have been obtained by fitting experimental energies in a number of hypernuclei over a wide range of mass. Calculations successfully describe various features including hyperon separation energy and single particle spectra of single-Λ hypernuclei throughout the periodic table. We also extend this formalism to double-Λ hypernuclei.
