We prove that the dynamical system characterized by the Hamiltonian HN ΣjN pj + μ∑j,kN (pjpk)1/2{cos[ν(qjqk)]} proposed and studied by Calogero [J. Math. Phys. 36, 9 (1994)] and Calogero and van Diejen [Phys. Lett. A 205, 143 (1995)] is equivalent to a system of noninteracting harmonic oscillators both classically and quantum mechanically. We find the explicit form of the conserved currents that are in involution. We also find the action-angle variables and solve the initial value problem in a very simple form.
