WebMar 7, 2014 · The coupled-channel method is a very powerful formalism for studying the structure of both strongly-bound nuclei [2], [3] and loosely-bound nuclei [4]. Here we propose a way to calculate the coupled-channel solutions in which all bound and continuum (resonant and non-resonant continuum) states are treated on the equal footing. WebDec 1, 2013 · Therefore, the equation becomes a coupled-channel one, and the number of channels depends on the size of the set of pseudo states. In coupled-channel problems such as that described above, if we apply the ordinary mesh-point representation for solving the equation, the dimension of the matrix becomes huge.
