Exclusive intermediate mass fragments(IMFs)are measured at forward angles forthe ~(40)Ar+~(nal)Ag reaction at 30 MeV/u.The impact parameter is determined using the totaltransverse momentum method and linear momentum transfer method.IMFs emitted at forwardangles mainly come from projectile fragmentation in peripheral collisions,while IMFs in centralcollision mainly come from decay of hot target-like sources.IMFs from both projectile-like andtarget-like sources are observed in mid-central collision.In addition,the third component,non-equilibrium mid-rapidity components are observed in central,mid-central and peripheralcollisions.
The intrinsic intermediate mass fragments (IMFs) were measured at the forward angles forthe ~ (40) Ar + ~ (nal) Ag reaction at 30 MeV / u.The impact parameter is determined using the total transverse momentum method and linear momentum transfer method. mainly come from projectile fragmentation in peripheral collisions, while IMFs in centralcollision mainly come from decay of hot target-like sources. IMFs from both projectile-like and target-like sources are observed in mid-central collision. In addition, the third component, non -equilibrium mid-rapidity components are observed in central, mid-central and peripheralcollisions.
