Abstract：
The in-plane and out-of-plane emission of light particles from ⁴⁰Ar+¹⁹⁷Au collisions at 25MeV/u was studied by means of coincidence measurement of light particles with two fission fragments.An in-plane enhancement was observed for mid-rapidity p,d,t,α particles,indicating a rotation effect in this reaction system.This enhancement becomes more obvious with the increase of mass of the particles,or with the increase of the impact parameters.It was also found that in-plane emission is dominant for projectile-like particles.
