= r * d77' I J(77p,7]', t'-T')dT'. 



Using the Laplace transforms, and putting

CO 



f*(^'>s) = I e"''' F*(7]',t')dt' , 



and so on, we obtain 



Let u (7]p), V (t]') be the Schmidt's fundamental functions of the nucleus 

 )(Vp' v',o). One has 



u (17') u^(T)')d7]' = , when r :)= q, =1 when r = q, 

 \[ 



v(77')Vj.(77')d77' = 0, when r ^ q, =1 when r = q. 



Therefore, we may write:
