Abstract
A new exactly solvable one-dimensional spin-3/2 Heisenberg model with SO(5)-invariance is proposed. The eigenvalues and Bethe ansatz equations of the model are obtained by using the nested algebraic Bethe ansatz approach. Several exotic elementary excitations in the antiferromagnetic region such as neutral spinon with zero spin, heavy spinon with spin-3/2 and dressed spinon with spin-1/2 are found.
