ANALYTICAL CALCULATION OF THE RADIAL INTEGRALS
Cai Chong-hai, Wang Si-wen
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1987, 4 (3): 284-298.  
Abstract370)      PDF (695KB)(950)      
In this work we describe a method from which one can conveniently derive the analytical expression of the radial integralsn1l1FLn2l2(q)≡∫0 (Rn1l1·(αr)jL(Kr)Rn2l2(αr)r2dr(q≡(K)/(α)). We also give the analytical expressions of for n1l1FLn2l2 L=0,1,2, and a general form of the radial integrals for all L,n1,l1,n2,l2 expressed by multi-sum.
