$\Lambda-$hyperon interaction with nucleons
  We study the interaction of $\Lambda-$hyperon with proton and neutron inside a nucleus within the framework of relativistic mean field formalism. The single particle energy levels for some of the specific proton and neutron orbits are analyzed with the addition of $\Lambda-$successively. We found that the interaction of $\Lambda$ with neutron is more stronger than proton.
