1 Werner Rosenheinrich Ernst - Abbe - Hochschule Jena First variant: University of Applied Sciences Germany TABLES OF SOME INDEFINITE INTEGRALS OF BESSEL FUNCTIONS Integrals of the type J 0 d or J 0 aj 0 b d are well-known Most of the following integrals are not found in the widely used tables of Gradstein/Ryshik, Bateman/Erdélyi, Abramowitz/ Stegun, Prudnikov/Brychkov/Marichev or Jahnke/Emde/Lösch The goal of this table was to get tables for practicians So the integrals should be epressed by Bessel and Struve functions Indeed, there occured some eceptions Generally, integrals of the type µ J ν d may be written with Lommel functions, see 8], 10-74, or ], III In many cases reccurence relations define more integrals in a simple way Partially the integrals may be found by MAPLE as well In some cases MAPLE gives results with hypergeometric functions, see also ], 96, or 4] Some known integrals are included for completeness Here Z ν denotes some Bessel function or modified Bessel function of the first kind Partially the functions Y ν sometimes called Neumann s functions or Weber s functions and denoted by N ν ] and the Hankel functions H ν 1 and H ν are also considered The same holds for the modified Bessel function of the second kind K ν When a formula is continued in the net line, then the last sign + or - is repeated in the beginning of the new line On page 41 the used special functions and defined functions are described *E* - This sign marks formulas, that were incorrect in previous editions The pages with corrected errors are listed in the errata in the end I wish to epress my thanks to B Eckstein, S O Zafra, Yao Sun and F Nouguier for their remarks 1

23 which means the loss of 10 decimal digits For that reason the value of such integrals should be computed by the power series or other formulas See also the following remark In the following the integrals are epressed by Z 0 and Z 1 Integrals with n 4 are written eplicitely: at first n = 0, 1,,, 4, after them n = 1, In the other cases the functions P ν n, Q n ν and the coefficients R n ν, S ν n describe the integral n J ν d = P ν n J 0 + Q n ν J 1 + R n ν Λ 0 + S ν n J0 d Furthermore, let n I ν d = P n, ν I 0 + Q n, ν I 1 + R n, ν Λ 0 + S ν n, I0 d Concerning 1 Z 0 d see 11, page 1 Simple recurrence formula: n J ν+1 d = ν n 1 J ν d n J ν 1 d n I ν+1 d = ν n 1 J ν d + n J ν 1 d The integrals of n Z 0 and n Z 1 to start this recurrences are already described Remark: Let F ν m denote the antiderivative of m Z ν as given in the following tables They do not eist in the point = 0 in the case ν + m < 0 However, even if ν + m 0 the value of F ν m 0 sometimes turns out to be a limit of the type For instance, holds J d = J 0 J 1 = F with lim F = With L ν,m = lim 0 F ν m for the Bessel functions J ν and L ν,m for the modified Bessel functions I ν one has the following limits in the tables of integrals The values L ν,m = 0 are omitted: L, 1 = 1/, L, 1 = 1/ L,0 = 1, L, = 1/8; L,0 = 1, L, = 1/8 L 4,1 = 4, L 4, 1 = 1/4, L 4, = 1/48; L 4,1 = 4, L 4, 1 = 1/4, L 4, = 1/48 L 5, = 4, L 5,0 = 1, L 5, = 1/4, L 5, 4 = 1/84; L 5, = 4, L 5,0 = 1, L 5, = 1/4, L 5, 4 = 1/84 L 6, = 19, L 6,1 = 6, L 6, 1 = 1/6, L 6, = 1/19, L 6, 5 = 1/840; L 6, = 19, L 6,1 = 6, L 6, 1 = 1/6, L 6, = 1/19, L 6, 5 = 1/840 L 7,4 = 190, L 7, = 48, L 7,0 = 1, L 7, = 1/48, L 7, 4 = 1/190, L 7, 6 = 1/46080; L 7,4 = 190, L 7, = 48, L 7,0 = 1, L 7, = 1/48, L 7, 4 = 1/190, L 7, 6 = 1/46080 L 8,5 = 040, L 8, = 480, L 8,1 = 8, L 8, 1 = 1/8, L 8, = 1/480, L 8, 5 = 1/040; L 8,5 = 040, L 8, = 480, L 8,1 = 8, L 8, 1 = 1/8, L 8, = 1/480, L 8, 5 = 1/040 L 9,6 = 560, L 9,4 = 5760, L 9, = 80, L 9,0 = 1, L 9, = 1/80, L 9, 4 = 1/5760, L 9, 6 = 1/560; L 9,6 = 560, L 9,4 = 5760, L 9, = 80, L 9,0 = 1, L 9, = 1/80, L 9, 4 = 1/5760, L 9, 6 = 1/560 L 10,7 = , L 10,5 = 80640, L 10, = 960, L 10,1 = 10, L 10, 1 = 1/10, L 10, = 1/960, L 10, 5 = 1/80640; L 10,7 = , L 10,5 = 80640, L 10, = 960, L 10,1 = 10, L 10, 1 = 1/10, L 10, = 1/960, L 10, 5 = 1/80640

24 In the described cases of limits of the type the numerical computation of F ν m causes difficulties, if 0 < << 1 Then it is preferable to use the power series, which has a fast convergengence for such values of With m + ν 0 holds 0 t m J ν t dt = m+ν+1 ν 1 k k k! ν + k! 4 k m + ν k k=0 and From this one has For instance, 0 t m I ν t dt = m+ν+1 ν F m ν = L ν,m k=0 k k! ν + k! 4 k m + ν k t m J ν t dt and F,m ν = L ν,m + J d = J 0 J = 0 t m I ν t dt = = = = It was a loss of seven decimal digits at = 000 This value may be found without problems by the power series: F 000 = = ] = = = In the previous value, signed by *, the last digit should be instead of 4 and the result had to finish with 8 The integrals with I ν may be computed in the same way This method can be used even if ν + m < 0 For instance, J 4 1 J 4 J 4 7 d = d d and the second integral is given in the following tables For the first one holds with the power series of the function J 4 1 J d = = d = 1 1 = d = = ln = = = = Here are no differences of nearly the same values = 4
