A combined theory for the overlap integrals of integer and non-integer n chi-Slater type orbitals (chi-ISTO and chi-NISTO) is presented. This approach is based on the use of lined-up auxiliary functions introduced by one of the authors. The suggested theory guarantees a highly accurate calculation of the overlap integrals for the arbitrary values of quantum numbers and locations of orbitals.
