Popis:	Excellent fits to on-shell t -matrix elements of a realistic local potential are obtained using a single-term energy-dependent separable potential in each of five channels. The comparison of half-off-shell t -matrix elements is also very favorable. The optical potential used contains absorption as well as spin-orbit contributions and is appropriate for the low energy n- 27 Al system. The separable potential is constructed so as to have the correct t -matrix pole locations and residues in each of the five channels.
