Session B07 - DNP: Relativistic Heavy Ions
MIXED session, Tuesday morning, April 18, 11:00
Room 16, Renaissance Hotel
Impact parameter selected transverse flow measuremens have been performed with the Miniball/Wall 4 \pi - detector systems. Techniques have been developed to extract the transverse flow independent of uncertainties in the reaction plane determination[1]. Interfering effects such as momentum conservation, particle-particle correlations and azimuthal non- uniformity in the detection array thereby are corrected. The precision in the technique allows accurate measurements of very small transverse flows. The measured transverse flow for the ^84 Kr+ ^197 Au reaction is quite large at E/A = 400 MeV and decreases with decreasing incident energy. At E/A=35, 55 and 70 MeV, the flow remains very small. The mass dependence of the collective flow for IMF will also be discussed. This work is supported by National Science Foundation. Reference: [1]P. Danielewicz et al, Phys. Rev. C38, 120 (1988)
