摘　　要：测量了α粒子与类弹产物的关联,得到的α粒子符合能谱呈现出类弹、类靶相继发射的特征;α粒子与类弹产物^(12)C的关联表明了弹核破裂(break-up)机制的存在.在类弹产物探测方向附近,观察到核的阴影效应.Energy and angular correlation of a particles in coincidence with projectile-like fragmentsare measured. The coincident spectra of α particle indicate the sequential decay pattern of the projectile-like fragments and the target-like fragments. The energy correlation between projectile-like fragment ^(12)C and α particles gives a strong evidence of projectile break-up. Near the direction of detected PLFS, the shadow effect is observed.
