: I'm searching for a good routine to calculate the
: spherical Bessel functions. All the routines I have
: found sofar are for the normal Bessel functions. The
: spherical Bessel functions are similar to those only
: for halfintegers. Normally these functions are called
: j_sub_l and n_sub_l, where normal Bessel functions are
: called J_sub_v and Y_sub_v. I would be grateful if
: anyone could help me. The routines should preferably be
: in fortran77 or fortran90.

IIRC there are some spherical bessel codes due
to A. R. Barnett, mostly published in Computers
in Physics Communications. The last program
I remember reading was titled COUL90. The
code itself is in F77. I believe this is the
code used in IMSL, for what it's worth.

Sorry, I don't have a *precise* reference, though.
