Abstract
For pt.I see ibid., vol.15, no.1, p.85 (1982). States of the 1D Hubbard chain with several pairs of complex wavenumbers are studied. The original set of Lieb-Wu equations (1968) is replaced by an equivalent set in which only real wavenumbers appear. These equations are reduced for the states in which the spin degrees of freedom are not excited. The energy-momentum dispersion for these states is also found.Keywords
