Query: Continuum-discretized coupled-channels method for four-body breakup
  reactions   Development of the method of CDCC (Continuum-Discretized Coupled-Channels)
from the level of three-body CDCC to that of four-body CDCC is reviewed.
Introduction of the pseudo-state method based on the Gaussian expansion method
for discretizing the continuum states of two-body and three-body projectiles
plays an essential role in the development. Furthermore, introduction of the
complex-range Gaussian basis functions is important to improve the CDCC for
nuclear breakup so as to accomplish that for Coulomb and nuclear breakup. A
successful application of the four-body CDCC to $^6$He+$^{12}$C scattering at
18 and 229.8 MeV is reported.
