Abstract
We explicitly construct the Rigged Hilbert Space (RHS) of the free Hamiltonian H 0. The construction of the RHS of H 0 provides yet another opportunity to see that when continuous spectrum is present, the solutions of the Schrödinger equation lie in a RHS rather than just in a Hilbert space.
