## Abstract

Errors to a previous paper (Canad. J. Math. (2) {\bf 49}(1997), 232--262) are corrected. A non-standard regularisation of the auxiliary operator $A$ appearing in Mourre theory is used.
 MSC Classifications: 35P25 - Scattering theory [See also 47A40] 58G25 - unknown classification 58G2547F05 - Partial differential operators [See also 35Pxx, 58Jxx] (should also be assigned at least one other classification number in section 47)
