The Gauss-Legendre quadrature formula is suggested to be
used for computation of the auxiliary integral B11 (y) in case when
y takes values near to zero. It is a111alytically shown and numerically
tested that the precision of the results raises as y approaches
zero. Owing to this property, this numerical procedure may be
helpful in computing overlap integrals over Slater type orbita1s
with nearly equal exponents.
