Recently a new direct CI method was proposed by Siegbahn. In his approach a large list of formulas containing one-electron coupling coefficients is made, creating storage problems and high I/O rates. A method to calculate these coefficients is described and tests performed showing that on the CRAY-1

β¦ Synopsis
The extended additional layer method EALM of calculating the coupling coefficient of arbitrarily shaped gratings is proposed. To determine the unperturbed field distributions, a grating region is replaced by a new uniform layer whose dielectric constant is the a¨erage ¨alue of the dielectric constant of a grating region in both the longitudinal and trans¨erse directions. The ¨alidity of this method is established by comparing the results calculated by partitioning the grating region up to fi¨e uniform layers.

The heat transfer coefficient mentioned in the title is calculated in this paper without to know the solution of the corresponding boundary value problem (neither in an explicit nor in an implicit form). This "direct method" makes use of a slightly modified form of the Merkin transformation which re
