Parameters NUMIN and NUMAX
For Coupled States
calculations the parameters NUMIN and NUMAX designate the minimum and maximum
value of the projection index nu. For collisions involving molecules with
half-integer spin, the minimum and maximum value of nu is equal to NUMIN+1/2 and
NUMAX+1/2. If you
are interested in cross sections out of or into a level with rotational
quantum number j, you must set NUMAX at least equal to j.
NUMIN should be a positive number (or zero), since the CS S matrices
for negative nu can be related to those for positive nu by symmetry and
thus need not be computed. If you set NUMIN=0, then you will compute
correctly cross sections for all j->j' transitions with j and j' less
than or equal to NUMAX.
For
Close Coupled
calculations the parameters NUMIN and NUMAX can be given any values, but are then set
internally to 0.
