Attending for greater simplicity only to a single ... it is assumed that the system admits of integrals of the form u = P, u = Q, &c., or as we may express it, of integrals P, Q, &c., where P, Q, &c. are rational and integral homogeneous functions of the set ( a , b , c ...), ... system is such that P, Q, &c. being integrals, ϕ (P, Q..) is also an integral. Then considering only the integrals which are rational and integral homogeneous functions of ...

The problem of the two-center hybrid integrals is solved in a general way for Slater-type atomic orbitals with integral effective quantum numbers. No other restrictions are placed upon effective quantum numbers and effective nuclear charges. The integrals are expressed linearly in terms of one type ... their computation. The treatment developed for the hybrid integrals is shown to be applicable also to the two-center Coulomb integrals and to the one-electron integrals.
