The Kołos-Wolniewicz (KW) wave functions are well known in quantum chemistry. In this work we study a possibility of generalization of KW functions towards greater flexibility and compactness. We report on a new approach to evaluation of integrals which allows numerical integration to be avoided. Some preliminary results illustrating an acceleration in energy convergence are reported.
