Target proximity effect and dynamical projectile breakup at intermediate energies Academic Article uri icon


  • Projectile binary breakup has been investigated in 58Ni+12C, 24Mg, 197Au at 34.5 MeV/A and 58Ni+70Zn at 40 MeV/A. The fragment angular distributions exhibit an anisotropic pattern showing that breakup is aligned with the direction of scattered quasi-projectile (QP). The correlation functions of the two heaviest fragments have been studied as a function of charge asymmetry. They suggest that the QP decays while still in close proximity of the target. The correlation between the charge and velocity of the two heavy fragments shows that the binary breakup of the QP might originate from an important deformation of the projectile by the target, and that the lighter of the colliding partners also contributes to the aligned emission pattern. 2004 Elsevier B.V.
