The possibility of an inverse scattering problem method application to the construction of exact solutions for a $D=5\mathrm{}$ dilaton-axion gravity system is demonstrated. By use of a Belinskiǐ- Zakharov L-A pair the massless solution with nontrivial dilaton and axion characteristics is constructed.
