Bound state calculations using separable expansion of the two-body t-matrix
It is shown that a separable expansion of local potentials (i.e., square well and Maltfliet-Tjon) using a method introduced by Adhikari and Sloan gives an efficient, exact numerically, method of solving three-body bound state. Contrary to the momentum-space basis functions in the work of Adhikari and Sloan, Y. Koike develops basis functions in configuration space since many two-nucleon potentials are given in that space. Legendre and Laguerre polynomials have been used respectively as base functions in this work. Following Koike`s approach, the authors` three-body calculations, with the above potentials, are stable to four significant figures. Such convergence is obtained with only five terms in the expansion.
