Abstract
Several methods of evaluating the Incomplete Gamma Function are compar ed according to accuracy and computation time. An improved algorithm i s presented which allows significantly faster computation of two-elect ron integrals on most vector computers, especially in the case of GLO functions. Parameters for F-0(t) are tabulated.
