The nuclear structures of Li() and Be() are studied within the microscopic cluster model, in which the clustering fragments e.g., triton, He, and even the single nucleons around the core are studied in the Li and Be systems. We obtain the energy spectra and wave functions of Li and Be, and the calculated energy spectra of the ground states and some of the excited states are consistent with experimental data. To investigate the cluster-formation probabilities, we calculate the reduced-width amplitudes of various binary partitions. The results show that the cluster structure is dominant in the low-lying states of Li(Be), including the ground state and the three lowest excited states. In some higher states around the single-particle thresholds, the components of structures, namely and in Li and in Be, are significantly enhanced.
