Light scattering by axisymmetric particles
           within a new approach to the T-matrix method

The code AXISYM0.FOR realises the new approach to the solution of
the light scattering problem suggested by Farafonov (Opt. Spectr.,
1999, submitted). Some features of the approach are described in
the first lines of the code. Below them one finds also the description
of the input and output parameters, and a list of some used subroutines.
The comments given through the code's text allow one to follow its
general structure.

The file IN contains the input parameter values for a test run. The
results of this run must be similar to those in the file OUT-TEST.
I have carefully checked the code by comparison with results derived
for spheres with the Mie theory and for spheroids of quite different
aspect ratios, sizes, compositions obtained with the T-matrix codes of
Barber & Hill and Mishchenko and with the SVM code of Voshchinnikov.
In general, the code created is at least as fast and correct as
the T-matrix codes mentioned. Though the code is a bit slower but
many parts of it can be easily speeded up.

The code is written in standard Fortran 77 and does not contain
any particular computational tools. However, please feel free to
contact me provided you meet problems.

The development of the new approach and the code was financially
supported by a grant of the Volkswagen Foundation (Germany).
