A FORTRAN PROGRAM TO CALCULATE BESSEL FUNCTIONS OF INTEGRAL INDEX AND COMPLEX ARGUMENT,

Abstract

Calculation of the radar cross section of a cylindrical shell plasma requires very accurate computations of the Bessel functions of the 1st, 2nd and 3rd kinds with complex arguments and integral order. FORTRAN II subroutines for the IBM-1410 computer have been n to calculate these functions. The zeroth and first order results agree with ten place tables pre pared by the National Bureau of Standards. Special methods are used to minimize round-off error in the recursive calculations of higher order. (Author)
