Dynamics of fragment capture for cluster structures of weakly bound 7Li

Abstract : Role of cluster structures of 7Li on reaction dynamics have been studied by performing exclusive measurements of prompt- rays from residues with scattered particles at energy, E/Vb = 1.6, with 198Pt target. Yields of the residues resulting after capture of t and 4;5;6He, corresponding to di erent excitation energies of the composite system were estimated. The results were compared with three body classical-dynamical model for breakup fusion, constrained by the measured fusion, and t capture cross-sections. The cross-section of residues from capture of and t agreed well with the prediction of the model showing dominance of the two step process - breakup fusion, while those from tightly bound 6He showed massive transfer to be the dominant mechanism.
