Abstract：
A concept of particle-group correlations is proposed in this paper. In according with the new concept, a new method of collective Dow measurement is constructed. Using the new method, the particle-group correlations arising from collective flow are studied with 4. data lbr 2.1A GeV Ne+NaF collisions at the Bevalac streamer chamber. Comparing with the Monte Garlo results, the collectivity of the particles in the final state of this collision is inferred in the range from 75% to 95%.
