  We prove the small energy scattering for the three-dimensional generalized
Zakharov system with radial symmetry based on the idea by Guo and Nakanishi
(2014), which treats the usual Zakharov system. For the proof, we use the
frequency-localized normal form reduction, and the radially improved Strichartz
estimates. The relation between the solution to the integral equations, which
includes the unusual boundary terms, and the original differential equations is
also considered.
