Abstract
Using the collective rotational transformation, R-x ( pi ), we construct tw o types of many-particle spin entangled states in terms of the bases of ang ular momentum uncoupling and coupling representations. The concept of signa ture is introduced. The entanglement properties of a four-particle system i s investigated by analyzing various subsystem reduced density matrices.
