Binding energy of aΛparticle in nuclear matter with Nijmegen baryon-baryon interaction

Abstract

The binding energy of a $\ensuremath{\Lambda}$ particle in nuclear matter ${B}_{\ensuremath{\Lambda}}$ is calculated with the models $D$ and $F$ of the NIjmegen baryon-baryon interaction. The result ${B}_{\ensuremath{\Lambda}}=30.6$ MeV obtained for model $F$ agrees with semiempirical value of ${B}_{\ensuremath{\Lambda}}$. and shows that suppression of $\ensuremath{\Lambda}\ensuremath{\Sigma}$ conversion in nuclear matter solves the hypernuclear overbinding problem.NUCLEAR STRUCTURE Binding energy of $\ensuremath{\Lambda}$ particle in nuclear matter, $\ensuremath{\Lambda}N$ interaction with $\ensuremath{\Lambda}\ensuremath{\Sigma}$ coupling.
