Query: A program for coupled-channels calculations with all order couplings for
  heavy-ion fusion reactions   A FORTRAN77 program is presented that calculates fusion cross sections and
mean angular momenta of the compound nucleus under the influence of couplings
between the relative motion and several nuclear collective motions. The
no-Coriolis approximation is employed to reduce the dimension of
coupled-channels equations. The program takes into account the effects of
non-linear couplings to all orders, which have been shown to play an important
role in heavy-ion fusion reactions at subbarrier energies.
