Suppose I have a cubic lattice of N^3 masses, M, each connected to six nearest neighbors with springs of constant k free to move but at rest. Now fire a single mass, m, with velocity v at surface of the lattice such that no rotation can be imparted to the cubic lattice. Let the fired mass bounce off a single lattice mass so that both masses move in the opposite direction.

Can we fire a mass at a lattice at rest and only produce translation of lattice with no or little vibration of the lattice?

I wanted to understand if there was a classical system similar to the crystal in the Mössbauer effect where we can have gamma emission with no crystal phonons produced.

Thanks for any help!
