ON REPORTING THE PRECISION OF SCATTERING CALCULATIONS

Scattering calculations often produce a series solution which, for the purposes of practical computation, requires restriction to a finite n umber of terms. The conventional approach simply specifies the arbitra ry number of terms to be included, and is of unknown accuracy. An impr oved procedure is proposed in which the number of terms included in th e calculation is defined by the accuracy required over the whole of th e ka range considered.
