Results in One, Two, and Three Dimensions, for Delta Functions, Square Wells, and Delta Shells, Respectively

摘要

I will outline three-particle calculations, and results, in one dimension [1–4] with delta-function interactions, in two dimensions [5–11] for square wells and in three dimensions [12] with delta shells. The presentation will be that of my own work, obtained together with colleagues. The initial approach is that of expansions of the wave function in terms of hyperspherical adiabatic functions, usually deduced from hyperspherical harmonics.
