“…On the other hand, the d wave quantities (l = 2) are sensitive both to the type of the input and to the way of allowing for inelasticity effects. This fact might be related to smaller absolute values and worse accuracy of the phase shifts 2 from [8,9] as compared with 0 . Nevertheless, in spite of large spread of the C 2 values presented in Tables 1 and 2, it is significant that in all cases the sign of C 2 (relative to C 0 ), which up to now has not been reliably established, turns out to be positive.…”
