MULTIPLICITY DEPENDENCE OF AZIMUTHAL DISTRIBUTIONS FOR AR-36-197 COLLISIONS AT E(AU)A = 35 MEV/

Collisions between Ar-36 projectile and Au-197 target nuclei at EIA =3 5 MeV have been studied with the Michigan State University Miniball, a 4pi phoswich array with a low detection threshold. Azimuthal distribu tions of charged particles with respect to the reaction plane are dete rmined via the transverse-momentum-tensor method. Dependence on the ki netic energy of the emitted particles, the collision geometry, and the associated charged particle multiplicity is investigated. Corrections for the intrinsic resolution of the experimental reaction plane deter mination are applied. Scaling implied by the coalescence model is expl ored and the data are compared to the results of microscopic calculati ons within the Boltzmann-Uehling-Uhlenbeck theory.
