A modified second Bron approximation is investigated. Comparisons with other Born, and exact calculations, are given for promblems of scattering by a spherical central potential. The choise of parameter which is argued by Garibotti and Massaro (4) and Woolings and Mc Dowell (8) from those of simplified second Born approximations by Holt and Moiseiwitsch (5) can be chosen easily in this case of our example.
