Abstract：
The in-plane and out-of-plane emission of light particles from ⁴⁰Ar+ ¹⁹⁷Au collisions at 25 MeV/u was studied by means of coincidence measurement of light particles with two fission fragments. An in-plane emission enhancement was observed for mid-rapidity p, d, t, αparticles, indicating that a rotational effect exists 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 for projectile-like particles the in-plane emission is dominant.
