We study a one-dimensional Bose system with repulsive delta-functioninteraction in the presence of an SU(2) intrinsic degree of freedom on thebasis of the coordinate Bethe-ansatz. The ground state and the low-lyingexcitations are determined by both numerical and analytical methods. It isshown that the ground state is an isospin-ferromagnetic state, and theexcitations are composed of three elementary particles: holons, antiholons, andisospinons. The isospinon is a triplet coupled to the "ferromagnetic"background anti-parallelly.Comment: 7 pages, incl. 3 figures, accepted by Europhys. Lett.
