GENERALIZED SU(2) COHERENT STATE OF SPIN SYSTEM
自旋体系的一般SU(2)相干态

This paper introduces the generalized SU(2) coherent state of spin system. Its squee ing and antibunching, and generation are discussed. It is shown that under the contraction of group SU(2) to the harmonic-oscillator group, the generalized SU(2) coherent state transforms to the generalized Glauber coherent state, the related results of the contraction are also given.
