The (Li(alpha, 2alpha)H)-Li-6-H-2 breakup reaction has been measured at E(alpha) = 77-119 MeV in coplanar, symmetric geometry. The projected energy spectra of the 2alpha correlation maps on the E1 axis were obtained and analyzed with DWIA and PWIA calculations. The positions of the quasifree-scattering peaks are well reproduced by both calculations, which at the higher incident energies reproduced well the widths of the experimental peaks. At lower energies, the widths obtained from the DWIA calculation are wider than those observed. Spectroscopic factors, S(alphad), for breakup into alpha + d deduced from the DWIA calculation averaged 0.58. Effective numbers of alpha-clusters, N(eff), deduced from the PWIA calculation averaged 0.22.
