    "abstract": "A complete realistic study of $_\\Lambda ^5$He hypernucleus is presented using\na realistic Hamiltonian and wave function. This study takes into account all\nrelevant dynamical correlations along with $\\Lambda N$ space-exchange\ncorrelation (SEC). We also compute $\\Lambda NN$ force and the corelation\ninduced by this force. The SEC affects the central repulsive $\\lambda N$\ncorrelation significantly at $r \\le 2.0$ fm, specially at its peak and in its\nvicinity. SEC significantly affects energy breakdown of the hypernucleus,\n$\\Lambda$-seperation energy, nuclear core (NC) polarization and density\nprofiles. A lage NC polarization is found with and without SEC, respectively.\nThe SEC effect is relatively large in two-pion exchange component of $\\Lambda\nNN$ force. Therefore, any attempt to pin down the strength of this force with\nno SEC would be flawed.",
