Query: Coupled reaction channel study of the 12C(alpha,8Be) reaction, and the
  8Be+8Be optical potential   Given the established 2 alpha structure of 8Be, a realistic model of 4
interacting alpha clusters must be used to obtain a 8Be+8Be interaction
potential. Such a four-body problem poses a challenge for the determination of
the 8Be+8Be optical potential (OP) that is still unknown due to the lack of the
elastic 8Be+8Be scattering data. The main goal of the present study is to probe
the complex 8Be+8Be optical potential in the coupled reaction channel (CRC)
study of the alpha transfer 12C(alpha,8Be) reaction measured at 65 MeV, and to
obtain the spectroscopic information on the alpha+8Be cluster configuration of
12C. The 3- and 4-body Continuum-Discretized Coupled Channel (CDCC) methods are
used to calculate the elastic alpha+8Be and 8Be+8Be scattering at the energy
around 16 MeV/nucleon, with the breakup effect taken into account explicitly.
Using the CDCC-based OP and alpha spectroscopic factors given by the cluster
model calculation, a good CRC description of the alpha transfer data without
any adjustment of the (complex) potential strength.
