hello:
    The following include recursive type formulae to calculate higher
angular momentum
integrals once you know the integrals over s-type functions.


Obara & Saika  J Chem Phys 84 (1986) 3963, J Chem Phys 89 (1988) 1540
Head-Gordon & Pople J Chem Phys 89 (1988) 5777
Ryu, Kim & Lee, J Comput Chem 14 (1993) 30

In general, if normalization is not mentioned, it is not done, and you
should add it yourself.
Any non-standard notation should be explained in the article.
