摘要：

We have calculated the energy per site for the ground state of the antiferromagnetic quantum spin chain with variable range exchange h(j - k) alpha sinh(2) a sinh(-2) a(j - k) in the framework of the asymptotic Bethe ansatz. By expanding it in powers of e(-2a), we have confirmed the value of the second-neighbour correlator for the model with nearest-neighbour exchange obtained earlier in the atomic limit of the Hubbard chain.
