Elastic scattering just means scattering of particles through collisions in which total kinetic energy is not lost. Think of the balls on a snooker or pool table as an analogy.

The scattering of light really is called scattering. If you are referring to a scattered reflection this can be called a diffuse reflection. Are you asking about different types of scattering such as Rayleigh scattering? Rayleigh scattering is an elastic type of scattering most well known for the blue color of the sky.
