摘要
We consider the computation of three functions which appear in the theory of synchrotron radiation. These areFp(x)=xK2/3(x) and Gp(x)=x1/3K1/3(x), where Kν denotes a modified Bessel function. Chebyshev series coefficients are given which enable the functions to be computed with an accuracy of up to 15 sig. figures.
