    "abstract": "We investigate the post-acceleration of the $^{10}$Be fragment in Coulomb\nbreakup reaction of the halo nucleus $^{11}$Be, assuming that the excitation of\nthe projectile is to states in the low energy continuum. The method used\nretains all finite-range effects associated with the interactions between the\nbreakup fragments and can use realistic wave functions for the halo nuclei. We\napply the method to compute the average momenta of the $^{10}$Be fragment at\nfour different scattering angles following breakup of $^{11}$Be on a Au target\nat 42 MeV/nucleon beam energy. Our results, which are in qualitative agreement\nwith recent precision experimental data, are consistent with the picture of no\npost-acceleration effect. The implication is that the breakup takes place on a\ntime-scale long compared to the collision time.",
