The leaky aquifer function W ( x , y ), an incomplete Bessel function which has had application in hydrology, is now also arising in electronic‐structure calculations on periodic systems. This work presents an expansion which improves the efficiency of calculation of W in the range where x and y are comparable and both are larger than unity. © 1997 John Wiley & Sons, Inc.
