The complete solution to the double-pulse problem has been derived. This solution includes higher-order corrections to the zeroth-order solution previously obtained by us (J. electroanal. Chem. 205, 21 (1986)). A general expression for these higher-order corrections based on a recursive relationship has been obtained. This allows us to compute the current response to any degree of accuracy by including as many corrections as necessary. Also, the computation process is facilitated because in these equations there are no involved integrals that must be evaluated numerically and only the well known function F(x) = pi1/2 x exp(x2) erfc(x) appears.
