We have investigated the prototype kaonic nucleus, $ppK^-$, using the methodof Antisymmetrized Molecular Dynamics (AMD). In the present study we use arealistic $NN$ potential with strongly repulsive core, and a Chiral SU(3)-based$\bar{K}N$ interaction which is energy-dependent and includes both $s$- andp-wave interactions. We find that no self-consistent solutions exist when therange parameter of the $\bar{K}N$ interaction is less than 0.67 fm. Due to thestrong repulsion of the $NN$ interaction at short distance, the two nucleons in$ppK^-$ keep a distance of about 1.2 fm and the total binding energy of $ppK^-$does not exceed about 50 MeV in the scope of our current analysis.Comment: 4 pages, 4 figures, Proceedings of IX International Conference on Hypernuclear and Strange Particle Physics (HYP2006
