    • A 4 kF charge ordering instability associated with the 1D electronic structure should occur at the q2 critical wave vector. But a 4 kF charge ordering instability whose origin lies in the occurrence of strong electron-electron interactions cannot account for the observation of a primary q1 /2 kF -like instability of the system.
