Abstract
We obtain a new exactly solvable K-plane vertex model. This 3D model i s one wih real Boltzmann weights and nearest neighbor interactions. Th e corresponding Yang-Baxter equation is proved. The Bethe ansatz has a lso been found, enabling us to completely investigate the phase diagra m in the ''free fermions'' case.
