Abstract：
The coincidence between projectile-like fragments and a-particles emitted from ²⁰Ne (14.7 MeV/u,192 MeV/u) + ⁵⁸Ni reactions has been studied. The coincident events were caused by the sequential decay of the excited primary fragments and by the "uncorrelated" coincidence between forward emitted α-particles and projectile-like fragments, which formed in a deeply dissipated reaction process. This reaction process means that the a-particle flied off the ²⁰Ne projectile in the initial stage of the reaction and then the residual ¹⁶O collided with the target nucleus dissipatively. We call it "incomplete deep inelastic process".
