Abstract

Bound state properties of few single and double-Λ\Lambda hypernuclei is critically examined in the framework of core-Λ\Lambda and core+Λ+Λ\Lambda+\Lambda few-body model applying hyperspherical harmonics expansion method (HHEM). The ΛΛ\Lambda\Lambda potential is chosen phenomenologically while the core-Λ\Lambda potential is obtained by folding a phenomenological ΛN\Lambda N interaction into the density distribution of the core. The depth of the effective ΛN\Lambda N potential is adjusted to reproduce the experimental data for the core-Λ\Lambda subsystem. The three-body Schr\"odinger equation is solved by hyperspherical adiabatic approximation (HAA) to get the ground state energy and wave function. The ground state wavefunction is used to construct the supersymmetric partner potential following prescription of supersymmetric quantum mechanics (SSQM) algebra. The newly constructed supersymmetric partner potential is used to solve the three-body Schr\"odinger equation to get the energy and wavefunction for the first excited state of the original potential. The method is repeated to predict energy and wavefunction of the next higher excited states. The possible number of bound states is found to increase with the increase in mass of the core of the hypernuclei. The Root Mean Squared (RMS) matter radius and some other relevant geometrical observables are also predicted.
