Query: Raynal's use of the word "aberrant" appears more appropriate for his
  ECIS formulation   Recently, we published a paper (Nucl. Phys. A 728 (2003) 65; see
nucl-th/0306068) presenting a new calculational method for nucleon-nucleus
elastic scattering at low energies. That method is particularly appropriate for
analyses in the region of narrow resonances. The method is based upon the
sturmian representation of the S-matrix, and allows inclusion of nonlocality
effects due to Pauli principle. It also provides a systematic identification of
narrow-resonance spectra and subthreshold bound states. A phenomenological test
calculation for low-energy (below 4 MeV) neutrons on 12-C (including the first
two excitations of the target) was presented to illustrate the validity of the
approach. The model calculation received a violent criticism (see
nucl-th/0312038) by the developer of a method (ECIS) which to date cannot
handle nonlocality effects and cannot be used easily to identify all narrow
resonances. We demonstrate that Raynal's opposition to our development is not
well founded by the arguments he presents. Indeed the work we published shows,
on rewording the title of nucl-th/0312038, that it is ``aberrant''
phenomenologically to analyze resonant low-energy nucleon-nucleus processes
with coupled-channel methods without taking into account the nonlocalities due
to the Pauli principle; problems typically encountered in the ECIS formulation.
