✦ Synopsis

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 < lcl < 1.
