abstract = {A diatomic elastic chain with nonlinear interparticle interaction
placed in a nonlinear external potential is considered. A detailed
classification of possible two-parametric traveling gap- and near-gap-soliton
solutions for this system is given for different relative strengths
of the nonlinearities. Analytical expressions are derived for traveling
near-gap solitons in the absence of an external field. (C) 2001 MAIK
