  Using a fully quantum mechanical post-form finite-range distorted-wave Born
approximation theory of Coulomb breakup, I study the parallel momentum
distribution of the core in the Coulomb breakup of suggested excited-state
one-neutron halo nuclei considered in their different bound excited states.
Narrow momentum distributions obtained in the present calculations for some
cases indicate the possibilities of the excited-state halo structure in the
nuclei under consideration and therefore favor the previous predictions.
