Abstract
Cross sections for direct and resonant breakup of radioactive nuclei produced in a transfer reaction have been measured. Breakup of into and cluster fragments via its resonant states of (4.57 MeV) and (6.73 MeV) in the continuum have been identified for the first time using the measured distribution of relative energy and the reaction value obtained from the coincident events. The breakup cross sections extracted from the efficiency corrected coincidence yield compares well with the results of the coupled-channels calculations. Significant cross sections for breakup of into its cluster fragments directly or through resonant states highlight the importance of the ground-state structure of as a cluster of and .
