We present a heuristic description of a practical theory of n-d elastic and breakup reactions. This is a new version of our three-body theory based on the Faddeev equation with a local potential in coordinate space. We reformulate our previous treatment as legible as possible, and made the following revisions: (i) The structure of the theory is centered on the elastic part of the Faddeev wave function. The breakup components are deduced as necessary ingredients of the elastic part. (ii) Since elastic channel must contain all possible spectator partial waves, it is treated in terms of a multi-channel coupled equation. (iii) Breakup processes to two-body partial waves other than ^lS_O are treated as the perturbation. (iv) The logarithmic singularities in the Faddeev Kernel in the breakup channel are studied in detail, and a practical method of solving our key equation is suggested based on the knowledge of the singularity structure of the solution. The presentation is detailed enough so that the formulas can immediately be transcribed to suit actual coding of a computational program.n-d elastic and breakup reactionsFaddeev equationLocal potential
