FOPI% (first order perturbation iteration method) is modified so that spin-factorable systems with unknown eigenfunctions can be treated (previous applications of FOPIM have been limited to systems xsitk eigenfunctions already known to all orders). The modification consists of [a) expressing rhe fir

The matrix elements of spin-dependent U (2n) generators are given explicitly. These matrix elements are expressed in terms of those of spin-independent U(n) and U (n + 1) generators, and can therefore be easily incorporated into existing unitary group approach based programs.
Based on various approaches, several different solutions to the smoothing problem have been given. The relationships between these solutions are not immediate, although they solve the same problem. Making use of a certain framework from scattering theory, we derive two families of solutions, with eq
