This routine uses Steedâs method to compute the values of the regular spherical Bessel functions j_l(x) for l from 0 to lmax inclusive for lmax >= 0 and x >= 0. The Steed/Barnett algorithm is described in Comp. Phys. Comm. 21, 297 (1981). Steedâs method is more stable than the recurrence used in the other functions but is also slower.
