    "abstract": "The conditions for optimal reflection-free complex-absorbing potentials\n(CAPs) are discussed. It is shown that the CAPs as derived from the\nsmooth-exterior-scaling transformation of the Hamiltonian,[J. Phys. B. 31, 1431\n(1998)], serve as optimal reflection-free CAPs (RF-CAPs) in wave-packet\npropagation calculations of open systems. The initial wave packet, can be\nlocated in the interaction region (as in half collision experiments) where the\nCAPs have vanished or in the asymptote where the absorbing potential non zero.\nAs we show the optimal CAPs can be introduced also in the region where the\nphysical potential has not vanished. The un-avoided reflections due to the use\nof finite number of grid points (or basis functions) are discussed. A simple\nway to reduce the \"edge grid\" reflection effect is described.",
