英文摘要	The transverse and longitudinal components of collective flow have been measured for the nuclear reactions Al-27(Ar-40, X), E = 25-85 MeV/nucleon and Ni(Ar-40, X), E = 36 and 65 MeV/u with the 4pi array Mur+Tonneau. Monte Carlo simulations show that, even for peripheral reactions, the transverse-momentum analysis method gives a better determination of the reaction plane than the method which uses only the projectile-like fragments. The measured in-plane transverse-flow values reach -30 MeV/c at low energies for Z = 2 particles and tends to zero around 85 MeV/u. Flow-angle values are in the range -65-degrees to -35-degrees. The azimuthal distributions of the measured charged products show that there is no squeeze-out of nuclear matter, but the reaction system has a rotation-like behaviour which increases with the impact-parameter value.
