Abstract
In this Letter we discuss the explicit Plancherel formula for the Bethe Ansatz eigenstates for the Hamiltonian of the infinite XXZ Heisenberg-Ising spin chain in the N-magnon sectors: N=2, 3,... In particular, we shall point out that a striking spectral phenomenon occurs when the coupling constant c is such that 0<|c|<1.
