Abstract : A procedure is studied for calculating the Bessel functions J sub nu (x) (nu real and non-negative) by utilizing their expansion in Laguerre polynomials. The errors, as estimated by the first neglected terms, are compared with the errors in the usual Bessel expansion for moderate x-values and are found to be more nearly uniform. The procedure appears to have some advantages over those now in use. (Author)
