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